The best indicator of the collapse of the US Dollar will be when all other countries besides the US avoid using the Dollar as a "World Reserve Currency", which means that it will no longer be a WRC. When that happens the debt the Obama administration is transferring to other countries which USED to use the Dollar as a WRC will not not be transferred any more and the result will be hyper-inflation as the value of the Dollar drops inversely proportional to the number of greenbacks in circulation.

It will cause a lot of civil unrest in this country, which is what I believe is what all that military training in L.A., Huston and Miami have been about: Getting ready for it.
