US pauses military aid to Ukraine

On the evening of 3 March 2025 a senior administration official, speaking on the condition of anonymity to discuss internal deliberations, confirmed to the Associated Press, Reuters, the Washington Post and CNN that President Donald J. Trump had ordered a pause of all US military assistance to Ukraine, including weapons and equipment already in the pipeline under prior congressional appropriations.¹ The official said the United States was “pausing and reviewing our aid to ensure that it is contributing to a solution.”¹ The pause followed the 28 February 2025 Oval Office meeting with Ukrainian President Volodymyr Zelenskyy and applied to both Presidential Drawdown Authority transfers from Department of Defense stocks and the Ukraine Security Assistance Initiative procurement pipeline; physical shipments were halted at the NATO logistics hub at Jasionka-Rzeszów in southeastern Poland.² Senate Armed Services Committee Chair Roger Wicker (R-Miss.) said he would “want to know more” about the rationale for the pause; Senate Majority Leader John Thune characterised the decision as “a pause, importantly, not a stop.”³

1. The pause halts further drawdown of US stocks under the Presidential Drawdown Authority of § 506(a)(1) of the Foreign Assistance Act of 1961, 22 U.S.C. § 2318(a)(1) — approximately $3.85 billion in authorised but undrawn PDA inherited from the 9 January 2025 final Biden tranche — and pauses obligations under the Ukraine Security Assistance Initiative.⁴⁵⁶ Items already transferred to Ukrainian custody continue in service; items in transit at Jasionka remain under US control.

2. Appropriations supporting Ukraine assistance under the Ukraine Security Supplemental Appropriations Act, 2024 (Pub. L. 118-50, signed 24 April 2024; $60.84 billion) remain available for obligation through their statutory period.⁶ A pause is operational, not a rescission; sustained withholding would raise questions under 2 U.S.C. § 684 (permitted deferrals) and § 683 (proposed rescissions).⁷

3. Ukrainian forces dependent on US-supplied air-defence interceptors (Patriot PAC-3 MSE, NASAMS) and precision munitions (ATACMS, GMLRS) carry replacement-rate risk during the pause. Replacement procurement from European producers operates on longer lead times than US drawdown of in-stock inventory.
