Nearly thirty years after he left office, the most important achievement of Jimmy Carter's time as president was his cementing the relationship with China that had begun under Richard Nixon and Gerald Ford. (Second-most important: Camp David accords between Israel and Egypt.

If they can, in 2039 we'll look back on this as something like the Silent Spring/Clean Air Act moment in American history, which began a change toward broad environmental improvement.

But let's hope the two sides concentrate on cleaning up for the long run.
