Once upon a time there was a popular song that asserted, "War! Huh!...What is it good for? Absolutely nuthin'! Say it again..." (insert blaring horns; I totally dislike blaring horns. And war.)
Nowadays people realize that war is 'good for' many things such as plundering other people's resources and establishing imperialist power bases on behalf of a 'new world order' of global domination, aka, a one world government. We now know that it's 'good for' a select few, but really really bad for anyone who gets in the elitist Vulcans' way and their 'vision' of The Great Plan of universal power.
Wonder how much oil and gas it would save the US to stop bombing other countries and bring our soldiers home from Middle Eastern sands?
Here's Rep. Dennis Kucinich telling of another 'use' for war, and he's right:
