It sounds crazy, but it is NOT improbable. If the world drops the dollar in trade (announces overnight) collapse WOULD start to happen overnight from the rapid market trading. Though the dollar is already being less used, an announcement would really kill it AND whole united states economy. The World hates USA, all the wars we started, CIA coup’s in Latin America, just imagine it. We’re the Nazi Germany of the 21st century; we’ll just be lucky that we should not be invaded.
