It's funny because you are what is wrong with America right now.
And why should we care about other countries' problems when we have plenty of our own? Child soldiers in Africa do not affect us in any way.
And this is why you will never join the military.
America is a world leader, that is a fact. It is honestly and wholeheartedly our duty to keep communism at bay and to help victims of crimes against humanity around the world. If we don't do it, who will? Would you rather us not help the people of the genocides of Rwanda, Darfur, or the Congo?
