That's just it. In the U.S. we the people uniquely

When Congressman Ron Paul ran for president it exposed many of his ideas to a broader audience, some of which make a lot of sense. I'm not saying I agree with everything he says, but his warnings for straying from the Constitution bear truth, even in recent history when we look at things like the Iraq war. At one point Bush specifically said we were on course for World War 3, presumably with Russia and China, backing up Iran who was in our sights for military action next.
