I really don't have time to write a long post right now, but I'll sum up what I was going to say and elaborate later.
1. Yes, my viewpoint is extremely selfish. After all, the American people are the ones who foot the bill interventions like the Iraqi conflict, I just think that the people of America and her allies are the only ones that the US military is beholden to.
2. To sum up my position, I think intervention itself is immoral, unless there is very, very strong evidence that an attack on the US or her interests is about to take place, and even that's something of a stretch. Defensive wars, or if we get declared war on by another nation, the US government and military are morally obligated to carry out.
Wer mit Ungeheuern kämpft, mag zusehn, dass er nicht dabei zum Ungeheuer wird. Und wenn du lange in einen Abgrund blickst, blickt der Abgrund auch in dich hinein. -Friedrich Nietzsche, Jenseits von Gut und Böse
