Apparently the Polish government sprang this announcement on us and there's a lot of stuff to do to those planes before they can get sent to Ukraine, i.e. removing newer avionics that we don't want to fall into Russian hands. There's also the problem of getting them to Ukraine without them being shot down on the way there.

The US answer wasn't "No" it was not as fast as Poland wants to do it.

The one excuse I don't actually care about is that Putin will see this as an escalation. Putin sees anything short of giving in to his demands as an escalation.

p.s.: I also wonder if Russia tried to use nukes, after seeing the condition of his army, is if they would even work.
