摘要：The Cuban missile crisis, which brought the United States and Soviet Union to the brink of nuclear war—as well as a dawning realization, now firmly enshrined, that neither side could gain a strategic advantage from the costly and destabilizing nuclear arms race—spawned a succession of strategic arms control treaties, starting with the 1972 Strategic Arms Limitation Treaty (SALT) and progressing through the current New Strategic Arms Reduction Treaty (New START). These agreements have reduced strategic nuclear arsenals dramatically, and—precisely because of that success—the United States must think very carefully about the next steps in this progression.
