February 2006 speech by Congressman Ron Paul before the US House of Representatives: http://www.house.gov/paul/congrec/congrec2006/cr021506.htm Short Excerpt: Our whole economic system depends on continuing the current monetary arrangement, which means recycling the dollar is crucial. Currently, we borrow over $700 billion every year from our gracious benefactors, who work hard and take our paper for their goods. Then we borrow all the money we need to secure the empire (defense budget $450 billion) plus more. The military might we enjoy becomes the backing of our currency. There are no other countries that can challenge our military superiority, and therefore they have little choice but to accept the dollars we declare are today's gold. This is why countries that challenge the system-- like Iraq, Iran and Venezuela-- become targets of our plans for regime change.
