Any mass murder of innocent people is horrible — whoever the target, whatever the motive, wherever it occurs.
In Moscow’s busiest airport yesterday, someone who apparently was a suicidal terrorist — the motive was not immediately known — slaughtered more than 30 innocent people and wounded about 180 other people by exploding a bomb in the international arrivals terminal.
Russia has enemies of many kinds. Security is usually very tight. But the Domodedevo Airport, 26 miles outside Moscow, evidently was not secure enough yesterday to avoid this horrifying tragedy.
What was the suicide bomber’s motive? What did the many people who died and the many more who were injured have to do with anything that drove the killer to destroy himself and others?
We live in a dangerous world — and many were killed randomly in Moscow, for no reason that was immediately clear.
