Ron Paul is right on this but he is wrong on national security.
If you limit National Security to Iraq, that may be true. But our monetary policies are just as much a threat. We cannot continue what we’re doing without consequences. If China unpegs the yuan, we’re screwed- if Saudi Arabia pulls their investments from our banks, we’re screwed. There’s quite a list of other financial vulnerabilities too, which become a security issue. Wars are expensive, especially when you fight with technology.
