The public needs to understand… America wants Ukraine to win, but America also wants to avoid a war with Russia. That tension has shaped every big decision since the first weeks of the invasion, when President Biden said a no-fly zone was off the table because it risked “World War Three.” The same basic idea, call it escalation management, explains the slow yes on tanks and long-range missiles, the fits and starts on aircraft, and today’s metered flow under President Trump.
What got sent, and when
Under Biden, the United States built the backbone of Ukraine’s air defense and ground-maneuver kit. Washington sent Patriot and NASAMS air defenses, HIMARS rocket launchers, Bradleys and Strykers, and, after months of debate, 31 M1 Abrams tanks. In April 2024 the administration also delivered longer-range ATACMS, and in mid-2023 it authorized 155mm DPICM cluster munitions after a tough internal fight. As of Jan 9, 2025, the State Department reported $66.5B in U.S. security assistance to Ukraine since Feb 24, 2022. That is the core military ledger of Biden’s term.
The long-range picture is what drew the loudest criticism. Biden said no to F-16s in Jan 2023, then opened the door in May 2023 and backed allied training and transfer. By mid-2024, deliveries and training pipelines were in motion. ATACMS followed a similar path, with limited-range variants first, and later shipments confirmed in April 2024. The logic was steady, not flashy. Move step by step. Expand Ukraine’s reach, but test the Russian reaction as you go.
What did not get sent also matters. The United States held back on MQ-1C Gray Eagle strike drones in 2022-2023 over escalation and tech-security risks. Washington never offered Tomahawk cruise missiles, which allies like the U.K. and France effectively substituted with Storm Shadow and SCALP. In late 2024 Washington let Kyiv hit certain military targets inside Russia with Western arms, but it has kept a ceiling on the longest-range strike combinations that could be read as direct U.S. enablement of a campaign deep into Russian territory. That mix of yes and not-yet is the tell.
Then came 2025
Donald Trump returned to the White House on Jan 20, 2025. He campaigned on ending the war “day one,” and his team quickly paused some U.S. weapons shipments approved in 2024, triggering a public fight over leverage, readiness, and end-states. Through the spring and early summer, shipments were on-again, off-again. By July and September, a new allied funding channel began to move U.S. munitions using European money, while Trump continued to resist large new U.S. appropriations. The Senate, on a bipartisan basis, still moved to tuck roughly $1B of Ukraine support into defense bills. Net-net, 2025 has seen fewer new U.S. dollars, more allied cash for U.S. kit, and a slower operational tempo out of Washington.
If you want the clean split in dollars: Biden’s term accounted for roughly $66.5B of U.S. military aid commitments through Jan 9, 2025. Under Trump in 2025, new U.S.-funded tranches have been limited, with deliveries relying mainly on previously approved funds and allied-funded buys via the new Prioritized Ukraine Requirements List. The Senate has pushed for about $1B in fresh authorization, but that is not the same as enacted, signed-into-law money. That is the ledger as of Oct 22, 2025.
Why so careful
Both administrations have watched the Kremlin signal nuclear red lines, then stage theater to back them up. Russia moved tactical nuclear weapons into Belarus in 2023 and ran exercises in 2024 practicing nuclear use scenarios. Moscow staged additional drills in 2025. These shows do not make nuclear use likely, but they raise the tail-risk. Washington’s answer has been to expand Ukraine’s punch, avoid a sudden leap, and let Russia’s leadership get used to each new rung. That is textbook escalation management.
What the front looks like
The line of contact has shifted yards and miles, not hundreds of miles. Russia captured Avdiivka in Feb 2024, then pressed west through small settlements. In summer 2025 Moscow claimed Chasiv Yar, a move Ukraine disputes but treats as a real threat to supply lines toward Kramatorsk and Sloviansk. ISW’s assessments this fall still frame the fight as grinding and positional, with Russian pressure continuing in the Pokrovsk direction. The map says “attrition.” So do the casualty and ammo curves.
What Ukraine built on its own
Kyiv has not waited on everything. Ukrainian engineers scaled a domestic long-range strike campaign, mostly with drones, that now reaches deep into Russia. 2025 raids have repeatedly hit refineries and depots. Reuters’ refinery data show about 17% of Russia’s refining capacity offline by late August, peaking near 21% at month’s end. Gasoline prices inside Russia ticked up. That is what a cost-imposition play looks like when you cannot mass brigades for a breakout.
Why not go bigger, faster
Here is the heart of it. If Washington handed over every long-range tool on Kyiv’s wish list tomorrow and blessed strikes across Russia’s interior with U.S.-supplied systems, Ukraine would hit more airbases, more logistics hubs, and more power infrastructure. It might also trigger Russian steps that cross the line we all fear. The reason has less to do with military asymmetry than with the political risk. The Kremlin keeps its nuclear rhetoric close at hand for a reason, and it has the delivery systems to make the threat credible. The United States keeps one eye on that tail-risk even when the probability looks low. That is why some systems have been sequenced, some have been withheld, and some have moved only through allies.
Is the stalemate on purpose
Not exactly. Washington is not trying to freeze the war. Washington is trying to deny the Kremlin a narrative that says “NATO is attacking Russia,” while making sure Ukraine does not lose. In practice that looks like steady air defense resupply, fires, and armor, cautious steps on long-range options, and yes, periods where the flow slows because domestic politics intervene. Biden’s team called it avoiding World War Three. Trump’s team calls it burden-shifting to Europe and using leverage to push talks. The effect at the front is similar. The line moves slowly.
Will Russia’s war economy crack on its own
Not soon, but pressure is building. Russia lifted defense outlays to about 6.3% of GDP in 2025, with defense and security together near 40% of federal spending. Growth was strong in 2024, then slowed sharply. By mid-2025 the IMF was marking down 2025 growth toward 0.6%-1.4% as high interest rates, labor shortages, and sanctions bit. The budget deficit widened again in 2024 and the government has been hunting for revenue, including tax rises. None of that means collapse this winter. It does mean a high-pressure economy that gets more brittle if the war drags through the next 1-2 years with continued strikes on energy assets and a tight labor market.
What happens next
Ukraine’s homegrown strikes have hurt Russian refining and forced costly patch-and-guard cycles. They have not forced Moscow to the table. The battlefield remains positional. The U.S. and Europe are still arguing about cost, risk, and timelines. In that world, the “just enough” approach looks set to continue. It is not satisfying. It is not fast. It is, for now, the way Washington squares two hard truths. Help Ukraine keep standing. Keep a nuclear-armed adversary from feeling cornered. We can keep doing both. The job is to hold steady.

|---|---|---|
| MQ-1C Gray Eagle armed drones | Withheld in 2022 | Tech security, escalation risk, survivability. |
