America still has much to decide. Among major issues, the US presidential campaign did not — and without comprehensive national review could not — clear up the daunting question of China. The policy differences between the two parties and their candidates, exaggerated for effect, were miniscule in comparison to the questions China raises. The ultimate stakes for America are huge. At some point a decision should be made on an overriding question that might roughly be put this way: If this planet is in fact big enough for not just one but two superpowers, can’t the US accept that a new Cold War is not inevitable? If so, what should be the optimal Sino-US relationship? What is in the national interest of each side and how large an area is the overlap of the two national interests?
