Why? It's more fun to invade and kill. When I visited my dad's unit in Afghanistan, they just finished building a 200,000 gallon reservior tank for a village. Some of Subzero's cousin's came and blew it up....so we cold fusioned their asses with 500 pound bombs. Little fuckers flipped us the bird from their bunker just before their bodyparts flew thru the air.
Besides, some fuck up will figure out how to create hydrogen bombs from water and then we'll have to bomb every country that borders the ocean, starting with those bastards in Cyprus.
