How about a democratic solution?
Since democracy is supposed to be the best way forward - and worth sacrificing the lives (nearly typed "livers" there, ooops!) of thousands of people for, surely we should let the amercans and chinese vote on the situation: what could be fairer?
On the one hand, we'd have 300 million americans and on the other 1200 million chinese - I think the outcome should be pretty clear. Isn't democracy a wonderful concept - especially when a small group of self-interested people can choose to only apply it when the results will be in their favour.
