Most air forces: 95% hamburger, 5% dangerous.
US, NATO, Austrailia, Japan, and Israel are unusual, in that 80% and up are dangerous.
South Korea, Taiwan, and India are, in my uninformed estimation, in the second tier. Say 50% dangerous.
the rest: see first line.
North Vietnam had one fellow who was darned dangerous. The above isn't to say that those guys aren't there. It is to say that there are not very many of them.
And it takes a lot more time to get a trained air force than a trained pilot. Knowing how to use those pilots can only start after you have them.
In WWII it took 3 years for the US to figure out targeting. It took 7 years in Vietnam.
Most NATO airforces & those of the likes of Australia or even Japan couldn't be expected to take on a formidable rival like China or Russia.....without Uncle Sam around.Australia's fleet is getting a bit too old as of now while potential rivals in S-E Asia are arming up while Japan has never really invested in offensive capabilities.It's F-15Js can hit deep into China-but atleast officially,they don't have any air to ground capabilities.
