Who's afraid of Austrailia?
Problem for us is, they are a strong ally, so anything they do gets uis dragged in.
I'm sure there's a LOT of diplomatic stuff going on all the time. If the US ever got really pissed, we could always do the protectionist thing and throw a 20% import tariff on all Chinese goods. It would hurt our economy, but not as much as it would smoke theirs........
