I love how people keep believing in these wunderwaffe. They can train them all they like, but these are obviously not going to make any significant difference.

There is absolutely no way in which a couple of airplanes will affect the war so drastically, furthermore it's impossible for the US to provide Ukraine with enough of them since it takes so much to manufacture and they need to have a stockpile, meanwhile Russia could use airplanes that are older since Ukraine basically doesn't have an air force and still get the upper hand.
