If USA government collapse dollar Russians will have serious problems. Just check oil/$ index and you will understand what i am talking about
Russia would be better off not holding dollar reserves if the US gov collapses.
It would be interesting to see what happens with billionaires and corporations stockpiling billions in us dollars if the dollar crashes.
Imagine a world where Bill Gates goes to sleep the richest man in the world one day & wakes up not very rich the next.
Do they realize the billions of dollars they're hoarding could be worthless if the gov defaults?
Do you really think the USG will default before most of the rest of the world? Really?
History (the best tool we have, not that good, but still...) suggests that when there huge crashes ( etc.) that it is usually the PERIPHERAL countries that suffer first.
