Western Arms Trade as Strategic Instrument — 2015–2026
Executive Summary
The United States is the world’s largest arms exporter, accounting for approximately 40% of global arms transfers (SIPRI 2019–2023). US, UK, French, and German arms exports function as strategic instruments — extending influence, building client relationships, sustaining defense industrial base, and enabling proxy warfare without deploying US/Western forces. The Yemen War (Saudi Arabia/UAE armed by US and UK while conducting operations producing mass civilian casualties), Gaza (US arms transfers to Israel during active IDF operations), and Ukraine (largest single arms assistance package in NATO history) are the primary active cases documenting the strategic and humanitarian dimensions of Western arms trade.
Key Judgment
Fact (High): The US government transferred approximately $75 billion in security assistance to Ukraine between February 2022 and the end of 2024 — the largest US security assistance program in history, surpassing the Cold War peak. This constitutes a proxy warfare operation by conventional definition: providing weapons, intelligence, and training to a third-party to fight a state adversary (Russia) without direct US military engagement.
Fact (High): US and UK governments continued arms transfers to Saudi Arabia and the UAE throughout the Yemen conflict (2015–present) despite documented use of those weapons against civilian infrastructure (hospitals, markets, water facilities) in confirmed airstrikes. The UN Panel of Experts documented specific munitions (JDAM kits, Paveway guidance systems, cluster munitions) in civilian strike sites traceable to US/UK supply.
Assessment (High): Arms transfers are the operational instrument through which Western states conduct proxy warfare — enabling strategic objectives (Ukrainian resistance to Russian occupation; Saudi containment of Iranian-backed Houthi forces) while maintaining formal non-belligerent status.
Case Studies
Yemen: Saudi Arabia / UAE (2015–present)
Fact (High): The US and UK maintained arms sales to Saudi Arabia and the UAE throughout the Yemen war, including precision-guided munitions used in airstrikes documented by the UN, Amnesty International, and Human Rights Watch as striking civilian targets.
Key evidence:
- JDAM guidance kits (US-manufactured) recovered from civilian strike sites by UN investigators
- UK Paveway IV guidance systems documented at civilian locations
- US Air Force tanker aircraft provided mid-air refueling to Saudi jets conducting strikes (withdrawn 2018)
- US military provided targeting assistance to Saudi-led coalition (withdrawn 2019 following Washington Post pressure)
- Congress passed resolutions invoking War Powers Resolution to end US involvement; vetoed by Trump (2019) and Biden (2021, partial reversal)
Scale: US arms sales to Saudi Arabia: approximately $64.1 billion FY2009–2019 (DSCA data); continued at reduced pace under Biden “review” with resumption of offensive weapons (500lb bombs) announced 2023.
Gaza: Israel (2023–present)
Fact (High): The US provided Israel with approximately $14 billion in emergency military assistance following October 7, 2023, including 2,000lb unguided bombs and precision munitions. Multiple documented strikes killing large numbers of civilians used US-supplied munitions verified by munitions identification.
Key evidence:
- 2,000lb MK-84 bombs confirmed in strikes on Rafah refugee area (May 2024)
- Leahy Law (prohibiting US military aid to units committing gross violations of human rights) invoked but not applied — State Department “inconclusive” findings despite UN documentation of violations
- Biden administration briefly halted one shipment of 2,000lb bombs (May 2024); resumed all other transfers
- ICJ provisional measures requesting humanitarian access (January 2024); US challenged application
Ukraine: Russia War (2022–present)
Fact (High): The US-led Western arms assistance program constitutes the operational backbone of Ukraine’s defensive capacity. Includes: HIMARS rocket systems; Patriot air defense; Abrams tanks; F-16 aircraft (2024); ATACMS long-range missiles; cluster munitions (2023); Stinger and Javelin anti-tank/air systems.
The proxy warfare frame: Ukrainian forces engage Russian forces using Western weapons, with Western intelligence support (satellite imagery, signals intelligence), while NATO states maintain formal non-belligerent status. This is operationally equivalent to the Soviet provision of weapons and advisors to North Vietnam, or the US provision of weapons to the Afghan mujahideen — a recognized form of proxy warfare regardless of the political framing applied to its justification.
SIPRI Data — US Dominance
| Supplier | Global Share 2019–2023 | Major Recipients |
|---|---|---|
| United States | 42% | Saudi Arabia, India, Australia, South Korea, UAE |
| France | 11% | India, Qatar, UAE, Greece, Indonesia |
| Russia | 11% (declining) | India, China, Egypt |
| China | 5.8% | Pakistan, Bangladesh, UAE |
| Germany | 5.6% | Ukraine, Hungary, Netherlands |
Open Gaps
- Gap: End-user monitoring — where do US-supplied weapons go after primary recipient; Yemen/Libya diversion documented, full picture unclear
- Gap: Leahy Law enforcement — which Israeli units were assessed under Leahy; what evidence was reviewed; State Dept. findings not public
- Gap: Ukraine arms inventory tracking — the US has acknowledged limited tracking of weapons once transferred; documented diversion to arms markets
- Gap: UK Paveway/Saudi — current status of UK legal challenges to arms sales (Campaign Against Arms Trade v. Secretary of State)
