i had a god laugh. "(Have you ever wondered why American - particularly Republicans - hate the French?)". Mate, do I have news for you; Nobody likes the french, nobody ever did tbh. As an Eu-citizen i can assure you that even their neighbours have a healthy dislike of the french.
But that was not my point. My point is that your point (2. Massive dollar devaluation would trigger chaos in world markets.) is and has already been happening for the last 10years. wake up man.
