God the military is so fucking stupid 
The US doesn't really lose in the same sense because they fight in other people's countries. Making huge areas uninhabitable or full of mutagens it's 100% fine by them. It's not just incompetence, they don't give a shit.
They also bring this attitude to their US bases, they're just more isolated.
