TWENTY-FIVE YEARS AGO Alexander Solzhenitsyn delivered the address at Harvard University’s commencement ceremonies. This year Ernesto Zedillo, past President of Mexico, provided the featured address at Harvard’s 352nd commencement. Except he didn’t. Zedillo did indeed deliver a speech: a workmanlike defense of international institutions, including, of course, the United Nations. President Zedillo, of consequence primarily because he was not corrupt and was relatively more committed to democracy than his predecessors, felt free to lecture a smallish crowd on the dangers of something he called aggressive unilateralism. Others might call this the closing of children’s’ prisons and the uncovering of war crimes, but Zedillo was there to upbraid the Bush administration–though his speech, like his presidency, will be remembered, if at all, only for its having ended without much noise.
