HONG KONG – In recent years, fears of a new cold war between the United States and China have been proliferating. But the tensions between the two powers would be better described as a “cool war,” characterized not by old-fashioned spheres of interest, proxy wars, and the threat of “mutually assured destruction,” but by an unprecedented combination of wide-ranging competition and deep interconnection.
NEW YORK – Until just a few years ago, it looked as if the problem posed by nuclear weapons had been successfully managed, if not solved. American and Russian nuclear stockpiles had been reduced substantially from their Cold War highs, and arms-control agreements were in place that limited both intermediate- and long-range systems. But all of this now could come undone.
