Also, I think you are jumping to a huge conclusion that BRICS countries are going to have a gold-backed currency, despite what they say. I don't think it's as easy as you think.
If you just said the U.S. made some big mistakes, I's agree. But your implied belief that all the countries besides the U.S. are infallible, honest, ethical, trustworthy, and are without a myriad of other problems is where you lose me.
