This is something US Treasury,  Fed,  US Government, and its people will have to worry about.  Printing money will depreciate one's currencies,  making the money useless in time to come.  The investors will be so scared to buy their Treasuries and invest money in their country and that would be a disaster for them. 

If we are not a big investor or invest nothing in the US,  what is there for us to worry about?    Should their money supply problem affect anyone else,  it would affect the big investors that bought lots of US Treasury.  They will bring the US the task.  Just grab a box of popcorn and watch the TV.
