Correct. That’s exactly how someone who understands warfare thinks.
Corrected. But it's not the Western way of war that they are being taught, it is the Anti-Western way. Wounded soldiers don't get air time on CBS/NBC/ABC. Dead soldiers do. Dead soldiers don't come back on the battle field.
In a short war, having lots of wounded soldiers on the other side helps. Not so much in a long war when modern medicine gets them back on the battlefield.
Guerilla wars are wars of attrition, dead is what counts.
