Washington and Kiev had disagreements over strategy, tactics, and timing during the conflict. While Ukraine wanted to attack Berdyansk and Bakhmut/Artyomovsk, the US preferred a focused assault on Melitopol. The Ukrainian leadership initially requested over 1,000 armored vehicles but received 1,500, some of which were criticized as unfit for combat. The US had to secure 155mm artillery shells from South Korea and couldn't fulfill Ukraine's request for F-16 fighter jets due to cost concerns and vulnerability to Russian air defenses.
