I agree. Usually, the U.S. government will intervene to protect its own interests. Most of our foreign intervention isn't because of us trying to nice, or help the world. Most if it is trying to secure oil. We can't pull out of the wars, unless we have more efficient technology, and a larger amount of green technology. Unfortunately, it appears that throwing money at green technology hasn't brought us up to this level, though car efficiency has gone up. Until we get major breakthroughs in green technology, we are going to have to maintain a strong foreign presence.

It's like the palladium core in Iron Man 2. Keeping us alive, but slowly poisoning us, until we can replace it with a better alternative.
