Both are important. Period.

There are a whole host of things we should get our priorities straight on: The Sudan, African AIDS, rising obesity rates, Chinese oppression, Russian mafia control of government, Mexican illegal immigration, potable drinking water, Brazillian shanty towns, etc etc.

Bro, the world is slowly getting better. Right now, I'm worried about MY country. MINE MINE MINE MINE MINE. USA USA USA and all the jazz. I am looking out for numero uno. And so are you, otherwise you wouldn't be posting on this board; instead you would dicth your family and join greenpeace, or the peace corps, or volunteer with the homeless. But I would bet that you do not devote a significant portion of your life towards bettering humanity in any substantial way other than talk about it. And neither do I except serve my Nation, which happens to aid in spreading access to potable water, builds schools throughout the world, prevents mass killings of innocents in multiple nations, donates billions to relief efforts (both through private and public funding), etc etc etc.

The world would be F-ed if America goes down hard. Absolutely totally F-ed. Screw potable water. Say goodbye to the world's economy. Say hello to the newly impoverished billions. Say hello to global strife like you have not seen since WW2. Say hello to the global rise of nuclear-armed muslim extremist states. Say hello to a whole new kind of China.

It has nothing to do with a million American citizens and everything to do with the repurcussions throughout the world. I just happen to only actually care about that first million.
