I believe there are historical processes unfolding and that America is essential to them. What's unfolding is the process of globalization. It is a good thing, and if we don't fuck it up and revisit the dark ages, it will bring a world with no war and no poverty within the lifetimes of many on this board.
But the process is not unfolding unopposed. There are those who see a very different future. A future that looks more like 1000 years in the past. So there will be perturbations along the way and many of them will be called wars. If they are fought to advance the cause of globalization and connectivity, then I say they are worth it. If parts of the world need to be dragged kicking and screaming into the 21st century, then so be it. The hard core ideologues determined to stop it - hunt them down and kill them.
There is a future worth creating out there and it's too important to give up to a pack of thugs in a time warp.
This is what Ron Paul can't see, and why he is an isolationist.
