Cool read, but I think the article takes things a bit too far in terms of "We can't fight a war!!!!!!" mentality.
Really, we have trouble fighting a limited war, and a counter-guerilla/insurgent war. But the same is true for just about everyone. By their very nature, guerilla fighters are going to be the most annoying/difficult to eliminate enemy, EVER, regardless of who you are and what equipment you're using.
