Because they have guns and so don't really need to fight anybody.
Sorry but its in the army is not really a good argument.
I'm sorry, but that's really just not true.
(a) I don't think there's any army anywhere that doesn't teach both armed and unarmed combat, so to say that an army also teaches armed combat doesn't in any way negate the teaching of unarmed combat. Your argument is a complete red herring.
You might as well have said something silly like, "The unarmed combat techniques that the U.S. teaches its troops is junk, because the U.S. Army also teaches its soldiers to shoot guns." The one has nothing to do with the other.
(b) When armies teach unarmed combat, of course they don't teach their soldiers things that they think will be ineffective. No country intentionally sends their young men and women off to die because of bad training, just like no army intentionally arms their troops with faulty weapons. If any army anywhere is teaching taekwondo, it's because they think that will help keep their soldiers alive.
