What was this great convocation about?

There was something oddly disproportionate about the just-concluded nuclear summit to which President Obama summoned 46 world leaders, the largest such gathering on American soil since 1945. That meeting was about the founding of the United Nations, which 65 years ago seemed an event of world-historical importance.

But this one? What was this great convocation about? To prevent the spread of nuclear material into the hands of terrorists. A worthy goal, no doubt. Unfortunately, the two greatest such threats were not even on the agenda.

The first is Iran, which is frantically enriching uranium to make a bomb, and which our own State Department identifies as the greatest exporter of terrorism in the world.

Nor on the agenda was Pakistan's plutonium production, which is adding to the world's stockpile of fissile material every day.

Pakistan is a relatively friendly power, but it is the most unstable of all the nuclear states. It is fighting a Taliban insurgency and is home to al-Qaeda. Suicide bombs go off regularly in its major cities. Moreover, its own secret service, the ISI, is of dubious loyalty, some of its elements being sympathetic to the Taliban and thus, by extension, to al-Qaeda.

So what was the major breakthrough announced by Obama at the end of the two-day conference? That Ukraine, Chile, Mexico and Canada will be getting rid of various amounts of enriched uranium.

What a relief. I don't know about you, but I lie awake nights worrying about Canadian uranium. I know these people. I grew up there. You have no idea what they're capable of doing. If Sidney Crosby hadn't scored that goal to win the Olympic gold medal, there's no telling what might have ensued.  (Continues here)
