i've seen the aircraft that the eu had sent to ukraine before. old cold war legacy systems that have seen no maintenance since the 1990's. the electronics and the cables eaten by mice. mice shit everywhere. trash. i've also seen the bundeswehr numbers for their aircraft and helicopters. of the machines they have on paper, only 50-70% are available and of those again less than half are combat-ready. combat-ready doesn't mean they could start immediately, it means they could be prepared in a few days. it's the same everywhere in europe. you also have to consider that the russians have modern anti-air weapons. the russians are the unbeaten tech leaders in missile weapons. their air defense systems are better than the israeli ones. and unlike israel, they have ammunition in stock for a long war. for an air war against russia, you would need thousands of replacement aircraft and replacement pilots. look up the us air war against vietnam. the americans lost almost 10000 aircraft and helicopters there. thousands of pilots. nato cannot afford that. they don't have the manpower, they don't have the infrastructure, they don't have the industrial base.
