Unless you think this war will still be going on in 2025 (It might!) there's no logical way Putin would have an ally as Congress has almost zero power over foreign policy.
They sure have a hand in voting for aid.
The United States has been a leading provider of security assistance to Ukraine, particularly since Russia launched its renewed and expanded invasion of Ukraine on February 24, 2022. From 2014, when Russia first invaded Ukraine, through October 14, 2022, the United States has provided more than $20.3 billion in security assistance “to help Ukraine preserve its territorial integrity, secure its borders, and improve interoperability with NATO.” Of this amount, the Biden Administration has committed about $17.6 billion in security assistance since the start of the 2022 war. FY2022 and FY2023 security assistance packages are mostly being funded via almost $28 billion in supplemental appropriations (P.L. 117-103, Div. N; P.L. 117-128; and P.L. 117-180, Div. B). FY2022 and FY2023 appropriations include a total of $14.05 billion to replenish Department of Defense (DOD) equipment stocks sent to Ukraine via presidential drawdown authority; $9.3 billion for DOD’s Ukraine Security Assistance Initiative (USAI; P.L. 114-92, §1250); and $4.65 billion in Foreign Military Financing (FMF; 22 U.S.C. §2763) for Ukraine and “countries impacted by the situation in Ukraine.” Supplemental appropriations also have included funds for U.S. European Command operations and related support for the U.S. military.
