The US may have lost hundreds simply because of it's commitments, the USAF flies all over the globe, it's involved in one kind of conflict or another, if not war then maintaining no fly zones also requires sustained effort, Russia and China also have large air arms but i doubt they suffer crashes anything like US and maybe not even like India...so your argument doesn't hold.... another interesting point to note, once i read that it takes something like $10 Million to train a Western combat pilot and a PAF pilot told me that it probably takes same if not more to train a pilot in the smaller budget airforce, since in the West and big budget airforces, they do a lot of training on simulators on the contrary, others have to fly extra training sorties to achieve the results.
