To me one thing is clear: once the USD collapses we're _all_ fu**ed up. Another thing that is quite likely is that it will end up in war once the USD will collapse. Besides that, it will pull other thing (not just currencies) with it. I think, one of the reasons the US have never been stopping to invest into military although people in the US die because of hunger and (on-existent) health care is that they need to be prepared for the day that the US is actually part of the third-world. Spain is called third world now by the US. As is Italy. The US wil be the same that day the USD goes down.
