RE:RE:RE:all the metalsI don't know if history is a great indicator here. The problem is that the US defaulting or even getting close to doing so, basically causes the world economy to shut down. There was a silly line going around a while back, that the US could just print a trillion dollar bill and pay off its debts. It was silly, but it wasn't *that* far off from reality, because what could the rest of the world do? They rely on trade with the US, and so they can't exactly just stop trading. They also can't exactly fight a military war, as the US military is bigger than the top-10 rest of the world combined.
It wouldn't come to that, because diplomatically the US alienate all its allies in the process, but it does serve to demonstrate that betting against them is a risky endeavour.
