The proposal to unilaterally end US blockades, embargoes, sanctions, and dismantle the "war machine" is strategically flawed, empirically unsupported, and likely to increase conflict.
This idea, advanced by socialist-leaning progressives, elements of the Democratic left (Congressional Progressive Caucus, Bernie Sanders-era amendments for 10%+ Pentagon cuts redirected to domestic programs, "defund the Pentagon" rhetoric), and anti-imperialist voices, rests on the view that the US is the primary driver of global instability. It calls for drastic military reductions, withdrawal from forward bases and alliances, ending economic pressure on adversaries like Russia, Iran, China, North Korea, Venezuela, and Cuba, and prioritizing diplomacy and domestic spending. While it correctly critiques waste, failed nation-building (Iraq, Afghanistan), and occasional humanitarian costs of broad sanctions, the overall strategy ignores power realities, history, adversary capabilities, and the mixed but useful record of these tools. It would likely produce more war, not less.[1]
US Military Dominance and the Costs of Unilateral Restraint
The United States possesses unmatched conventional and power-projection capabilities. In 2025, US military spending was approximately $930–954 billion—about 33% of global totals (~$2.9 trillion), 2.8 times China’s estimated $336 billion, and far ahead of Russia’s ~$190 billion. This equates to roughly 3.1% of US GDP, far below Cold War averages (often 5–9%) or peaks like 13+% during Korea. Global Firepower 2025 ranks the US #1 by a clear margin, with advantages in carrier strike groups (~11 nuclear carriers vs. China’s growing but less experienced fleet), stealth aviation, nuclear triad, satellites, cyber, logistics, and ~800 overseas facilities enabling global reach. China excels in mass (largest navy by hulls, hypersonics, A2/AD missiles) and is rapidly modernizing for a Taiwan contingency; Russia maintains a potent nuclear/hybrid threat but has been attrited in Ukraine; Iran relies on asymmetric proxies and missiles.[2]
The "war machine" underwrites the post-1945 order: secure sea lanes (80%+ of world trade moves by sea through vulnerable chokepoints like the Strait of Hormuz, Malacca, and Taiwan Strait), deterrence of great-power war, and alliance credibility. US forward presence stabilized Western Europe, Japan, and South Korea. Unilateral deep cuts (proposals have included $350 billion reductions or slashing to <2% GDP) would create power vacuums. Adversaries do not reciprocate restraint; they exploit it. Russia’s 2022 Ukraine invasion followed the chaotic Afghanistan withdrawal. China’s militarization of the South China Sea and threats to Taiwan accelerated amid US debates over retrenchment. History is littered with examples: 1930s Western disarmament and appeasement enabled Axis aggression; post-Vietnam Soviet advances in the Third World; the "peace dividend" of the 1990s preceded 9/11 and renewed great-power competition.
Ending this posture risks regional wars, energy shocks, trade disruptions hitting the US economy, ally nuclear proliferation (Japan, South Korea, possibly Germany), or "Finlandization" of Europe and Asia under Chinese/Russian influence. The Pax Americana correlates with fewer great-power wars, a boom in global trade and democracy (from ~17 to 88 liberal democracies post-WWII in some counts), and lower overall battle deaths. Pure isolationism or "restraint" assumes benign adversaries acting in good faith—an assumption contradicted by Xi Jinping’s explicit revisionism, Putin’s revanchism, and Iran’s ideological export of revolution via proxies.[3]
Sanctions, Embargoes, and Blockades: Imperfect but Valuable Leverage
Economic statecraft provides a middle option between empty diplomacy and kinetic war. Comprehensive studies (Hufbauer et al. and updates) find sanctions achieve at least modest policy success in roughly 34% of cases historically, rising toward 40% post-1990 with better design: targeted/smart sanctions on elites, multilateral coalitions, higher pre-sanction trade dependence, and swift implementation. They reliably damage targets—reducing GDP growth, trade volumes, FDI, and regime resources—with low and short-lived costs to senders. Effects can persist post-lifting due to lost networks and adaptation costs.[4]
Examples: Sanctions slowed Iran’s nuclear program (buying time for diplomacy or other options); post-2022 measures on Russia forced oil sales at discounts, technology shortages, and diverted trade, degrading military reconstitution despite Chinese/Indian circumvention. Historical naval blockades complemented military power effectively (American Civil War, WWII Allied efforts). They constrain funding for missiles, terrorism sponsorship, and proxies. Pure diplomacy without costs frequently fails against autocrats who view concessions as weakness (Iran deal debates, North Korea, pre-invasion Russia). Ending sanctions, embargoes, and blockades removes this lever entirely, leaving adversaries freer to build war chests, proliferate, and aggress. They are not a panacea—regime change is rare, evasion grows (parallel financial systems, smuggling), humanitarian costs exist, and "rally-around-the-flag" effects occur—but abolition is worse than reform. Multilateral, targeted use paired with credible military backup works better than unilateral idealism.[5]
Ideological and Practical Problems
The framing of the US as an inherently aggressive "empire" or "war machine" driving global chaos overstates blowback while understating adversary intent and capability. It romanticizes diplomacy in an anarchic international system (realist insight from Thucydides onward). Interventions have mixed records—successes in the Gulf War, Kosovo air campaign, counter-ISIS coalition; failures in prolonged occupations—but the response should be smarter strategy (lethality, alliances, deterrence over endless nation-building), not abolition. Domestic priorities matter, but entitlements dwarf defense; cuts won’t automatically fund utopia without addressing fiscal realities, and defense R&D has historically spun off civilian tech (GPS, internet roots, jet engines).
This approach risks higher overall violence by eroding deterrence. Adversaries are building capability and testing limits now. A restrained US would likely face more crises, not peace. Targeted reforms—auditing Pentagon waste (failed audits are real), pruning ineffective sanctions, avoiding quagmires, focusing on China peer competition—are prudent. Unilateral disarmament and abandonment of economic tools is not. It substitutes hope for strategy in a world of revisionist nuclear powers. Peace through strength, updated for new technologies and alliances, has a stronger empirical and historical track record.

Updated Military Balance and Spending
According to SIPRI’s April 2026 release, world military expenditure reached approximately $2.887 trillion in 2025, a 2.9% real-term increase and the 11th consecutive year of growth. The United States accounted for roughly one-third (~$954 billion, or 33%), though this was down 7.5% from 2024 due to timing of aid packages. China rose 7.4% to an estimated $336 billion. Russia increased 5.9% to ~$190 billion (7.5% of its GDP). Europe surged 14% to $864 billion amid the Ukraine war and NATO rearmament. Projections for 2026 show US spending exceeding $1 trillion, with potential further rises.[1]
The US retains decisive qualitative and power-projection advantages: 11 nuclear-powered aircraft carriers (vs. China’s 3), superior stealth aircraft, nuclear submarines, satellite networks, logistics, and ~800 overseas facilities. China leads in raw quantities (largest navy by hull count, massive missile forces, troop numbers) and is rapidly modernizing—building naval tonnage at 2+ times the US rate in recent years. It is optimizing for a Taiwan contingency with anti-access/area-denial (A2/AD) systems. Russia’s forces have been heavily attrited in Ukraine (high equipment and manpower losses) but retain nuclear parity and hybrid capabilities. Global Firepower and other 2026 indices continue to rank the US #1 by a wide margin, China #2, Russia #3.[2]
Unilateral deep cuts to the US “war machine” (proposals from progressive voices have included halving the budget, capping around $750 billion, or 10–50% reductions redirected to domestic programs) would widen vulnerabilities in key theaters. China’s military modernization is explicitly aimed at altering the status quo in the Western Pacific. Russia’s invasion of Ukraine followed perceived Western weakness after the Afghanistan withdrawal. A restrained posture risks eroding extended deterrence, encouraging ally proliferation (South Korea, Japan), and raising the probability of regional wars that could draw the US in under worse conditions.
Sanctions, Embargoes, and Economic Statecraft: Recent Evidence
Sanctions are imperfect but impose measurable costs. On Russia post-2022, cumulative impact is estimated at €1.3 trillion. Sanctioned imports dropped sharply (55% direct decline, net ~27% after third-country rerouting through China, India, Turkey). Affected Russian firms saw ~14% output declines, with ripple effects along military supply chains. High-tech items (microelectronics) now cost 5x+ via evasion networks. Oil revenues have faced discounts, shadow fleet complications, and direct disruption from Ukrainian “kinetic sanctions” (drone/missile strikes on refineries), which reduced Russian refining capacity significantly in 2026 and forced export bans on diesel/gasoline. Russia’s long-term growth appears capped at 1–1.5%; sanctions have not collapsed the economy or ended the war but have degraded its ability to sustain high-intensity conflict indefinitely.[3]
Broader studies (including GAO reports) confirm export controls have hindered—though not fully blocked—Russia’s acquisition of critical technologies. Historical patterns show sanctions succeed modestly (~34–40% of cases) when multilateral, targeted at elites, and backed by credible military options. They serve as a costly middle ground between diplomacy and war. Comprehensive embargoes or blockades (e.g., historical naval examples) amplify leverage when paired with military power.
The restraint perspective (e.g., Quincy Institute) argues broad sanctions are often counterproductive: they cause humanitarian harm, provoke rally-around-the-flag effects, drive targets toward adversaries (Russia-China alignment), and represent “war by other means.” They advocate lifting many country-wide regimes (Cuba, Iran, Venezuela) and prioritizing diplomacy. Progressive proposals in Congress have aligned with this—opposing secondary sanctions, pushing to review or lift measures on Latin America, and emphasizing domestic redirection over “endless militarism.”
Counterpoint: Removing these tools entirely leaves fewer options against revisionist states pursuing nuclear breakout (Iran), territorial revision (China on Taiwan, Russia in Europe), or proxy warfare. Pure diplomacy without costs has repeatedly underperformed against autocratic regimes that treat concessions as weakness. Evasion is real and growing (parallel systems, crypto, re-exports), but the data show persistent net damage and higher costs for the target. Multilateral, smarter, targeted sanctions paired with alliances outperform unilateral idealism or total abandonment.
Broader Strategic Context and Rising Threats
The post-1945 US-led order (alliances, forward presence, secure sea lanes for ~80% of global trade, technological edge) correlates with no great-power wars, a massive expansion of global trade/democracy, and lower overall battle deaths—until recent reversal. Data from 2021–2025 show over 930,000 battle deaths and a record ~65 state-based conflicts in 2025. This trend contradicts the assumption that US retrenchment automatically produces peace. Adversaries are not status-quo powers waiting for American restraint; Xi, Putin, and Iran’s leadership articulate explicit revisionist goals.
Military strategy and tactics implications: The US “war machine” funds integrated deterrence—combining conventional overmatch, nuclear triad, cyber/space assets, long-range precision strike, and ally interoperability. It complicates adversary planning (e.g., US submarines and distributed forces vs. Chinese A2/AD). Ending forward posture and deep budget cuts would favor mass-based strategies of near-peer competitors in littoral or regional fights. Reforms make sense: audit waste (repeated failed audits are real), sunset ineffective sanctions, shift from endless occupations to lethal forward defense, emphasize China pacing, and demand more from allies (many NATO members now exceed 2% GDP). But radical unilateral disarmament substitutes hope for strategy in an anarchic system.
In short, the empirical record favors peace through strength updated for drones, AI, hypersonics, and economic coercion, rather than abrupt abandonment. Targeted improvements address real flaws (Iraq/Afghanistan nation-building failures, sanctions humanitarian costs, procurement bloat). The socialist/progressive vision of ending blockades, sanctions, and the military apparatus wholesale would likely increase great-power risk and reduce US leverage. The world is becoming more contested and violent, not less—precisely the environment where credible tools of statecraft remain essential.
References
Here are the primary references supporting the key factual claims in the most recent response on US military spending, the strategic value of sanctions/embargoes, global conflict trends, and the critique of unilateral restraint. These draw from official 2025–2026 data releases (current as of November 2026).
Military Expenditure and Balance
- SIPRI (Stockholm International Peace Research Institute): "Trends in World Military Expenditure, 2025" (published April 2026). World total reached $2,887 billion in 2025 (+2.9%, 11th consecutive year of growth). US spending: $954 billion (down 7.5%, ~33% of global total). China: $336 billion (+7.4%). Russia: $190 billion (+5.9%, equaling 7.5% of Russian GDP). Europe: $864 billion (+14%). NATO total: $1,581 billion.[1]
This matches the figures cited closely. The report emphasizes Europe’s surge due to the Ukraine war and Asian growth driven by China. US advantages in carriers, stealth, submarines, logistics, and overseas basing remain standard in assessments from the International Institute for Strategic Studies (The Military Balance) and Global Firepower Index 2026 (US ranked #1, China #2, Russia #3 with noted Russian attrition in Ukraine).
Sanctions Impact on Russia and Effectiveness
- EU High Representative Kaja Kallas statement (June 2026): Western sanctions have cost Russia an estimated $1.2–1.5 trillion cumulatively. Additional analyses cite ~€1.3 trillion in broader economic impact, including lost output, discounted oil sales, technology shortages, and supply-chain disruptions.[2]
- Academic firm-level studies (e.g., on Russian imports and output): Direct sanctioned imports dropped ~55%, with net decline ~27% after third-country evasion (China, India, Turkey). Affected firms saw ~14% output declines, with persistent military supply-chain effects and higher costs (5x+) for high-tech items. Ukrainian strikes on refineries further reduced capacity in 2025–2026.[3]
Historical sanctions success rate: Gary Clyde Hufbauer, Jeffrey Schott, and Kimberly Elliott (Economic Sanctions Reconsidered, Peterson Institute for International Economics). Overall success rate ~34% across cases, rising to ~39–40% post-1990 with better-targeted, multilateral designs. Success is higher for modest goals and when paired with other tools; comprehensive studies confirm measurable economic damage even with evasion.[4]
Critiques of broad sanctions (humanitarian costs, rally-around-the-flag, driving Russia-China alignment) often come from the Quincy Institute for Responsible Statecraft and progressive congressional analyses.
Global Conflict Trends
- Uppsala Conflict Data Program (UCDP) / PRIO: "Conflict Trends: A Global Overview, 1946–2025" (2026 release). Record 65 state-based conflicts in 2025 (highest since records began in 1946). Approximately 245,000 battle-related deaths in 2025 (one of the deadliest years post-Cold War, driven by Ukraine, Sudan, and Gaza-related violence). Eight interstate conflicts—double prior years and the highest since 1946. One-sided violence also at post-1994 highs.[5]
This data contradicts the notion that US retrenchment automatically reduces global violence; the trend shows rising contests in a more contested environment.
Additional Strategic Context
- Analyses of “peace through strength,” deterrence, and the post-1945 order often reference works such as Michael Beckley (The Myth of Entangling Alliances or Unrivaled), Elbridge Colby on integrated deterrence, and RAND/Atlantic Council reports on China-Taiwan scenarios and Russian revisionism.
- Progressive proposals to cut the Pentagon budget significantly (10–50% reductions, redirect to domestic priorities, lift many sanctions) appear in materials from the Congressional Progressive Caucus, Bernie Sanders-aligned amendments, and “defund the Pentagon” rhetoric.
- Counter-arguments favoring restraint (ending the “war machine,” prioritizing diplomacy over sanctions) are prominently advanced by the Quincy Institute.
The response synthesized these into a realist critique: sanctions and military power projection are imperfect tools but provide leverage and deterrence in an anarchic system with revisionist nuclear-armed states. Unilateral abandonment would likely create vacuums that adversaries exploit, as seen historically (1930s disarmament, post-Afghanistan withdrawal dynamics).
