Just a little more evidence going back to a post I made a few days ago... To me, it's a rather convincing argument, especially if you consider that we've literally invaded every single country that has threatened to get off the petrodollar system.
And, speaking of the petrodollar system, here's an interesting little video that says what I've been saying for YEARS... the collapse of the dollar will occur the second that enough countries decide to abandon the petrodollar system and the US dollar as the reserve currency... and many countries cant to get off of it, not only because they're getting fed up with the American dominance of this system, but because the dollar is plummeting in value. China and Russia have already gotten away from this system in their bi-lateral trade... Of course, unlike Iraq and Libya, we can't just go in there and kick their ass. I suspect that more counties will enter in to trade agreements with them, since now smaller nations will have the protection from two major superpowers.
When I have this conversation with people, a question that I commonly get is "well, why aren't countries getting out of the dollar faster if they think it's going to collapse?" The answer is very simple. International markets work very much like Wall Street. If one country were to all the sudden just 'bail out' of the dollar (besides taking a temporary (but recoverable) financial punch in the gut) it would cause MASS panic that would seep through the entire system. To expand upon my analogy, prior to the original great depression, JP morgan, the Rockerfellers, the Rothschilds, and several other prominant bankers slowly and quietly started selling off their holdings. If they'd done this all at once, the panic would have triggered the decline of the system at an inopportune time. By 'sneaking out' of the market, they were able to maintain control of it, maximize their profits and minimize their losses. Then, when the system collapsed, they were able to reap MASSIVE benefits (if you're not familiar with this story, then I suggest you do some research into the original great depression). To put it another way, if you're trapped on a sky skraper and you notice a prominent threat, like a fire or a bomb, you don't want to scream about it at the top of your lungs, because the panic that creates will make it harder for you to ensure your own safety. What an self-preserving individual would do is wait until he safely got to the bottom of the sky scraper before alerting others.
This is very much what's going on with the US economy. In fact, just the other day, China announced that it will Reduce its U.S. Debt Holdings by $249 Billion. Small as it might be in the grand scheme of things, this is a sharp reversal of trends, and effectively, the first step towards the elevator. Many people are still suspicious that Japan might need to cash in on its treasuries to help pay for the recovery too... This remains to be seen, but it could mean some pretty rough times if that does happen.
