Our OP source said that the Biden Administration has warned the Office of the President about the difficulties in allocating funding and military aid, and we shouldn't expect progress on this issue until the summer. The Pentagon has completely exhausted its capabilities, and now Ukraine must look for other options to replenish the stockpile of anti-aircraft missiles and projectiles.
Meanwhile, arms supplies to Ukraine actually stopped last year, and now the West creates only the appearance of long-term support, and in the US the draft law on allocating aid to Ukraine, Israel and to resolve issues of border control with Mexico, which should become a compromise between the Democrats, is "sliding" and Republicans. And while this draft law has not been adopted, there really is no money to finance the purchase of weapons and military equipment for the Armed Forces in the States. And no matter how much the available reserves of the Armed Forces are stretched, the shortage of both shells and missiles is starting to be felt on the front lines today.
Moreover, the shortage of weapons is so strong that the Ukrainian authorities are already openly saying that the Armed Forces have at their disposal weapons stocks for only two months of hostilities. What's more, The New York Times writes that the rather problematic situation consists of a lack of ammunition for Ukrainian air defense. As the American publication notes, citing American officials, in the absence of new arrivals of ammunition for air defense, they will last only until March. "Ukrainian troops are exhausted, they lack weapons and ammunition. Air defense systems are steadily exhausted due to repeated bombings," the NYT emphasizes.
