China isn't seeking global hegemony. Of course not. Every nation wants something. America wants something. Russia wants something.
China is no exception.
China wants what is rightfully hers returned. No more and no less. China is passionate as an irredentist power, not as an expansionist power. China is not now a threat on the order of the Soviet threat, so that the question of appropriate behavior focuses on the moral, not the strategic, question. Try William F. Buckley, circa 1997.
