Don't tell me that they only thought that the Chinese might do something like that now, it's not as if that wasn't a predictable move.<p><i>Of course</i> the Chinese will use US debt as a weapon, just like the US would use it if the situation were reversed.<p>Don't forget that Russia crashed because of being unable to keep up with the spending patterns of the US, not because of some moral overweight or military pressure. Their economic structure wasn't capable of matching the US and the Afghanistan war (the previous one, the one 9/11 was an outgrowth of) sealed the deal.<p>The US is in between a rock and a hard place economically when confronted with China, a massive sell-off could destabilize the dollar to the point that traders would favour other currencies (most likely the Euro), and that would accelerate the fall. If you live in a glass house you should not throw with stones.
