LIKE PIRATES, terrorists are supposedly hostis humani generis — the "enemy of all mankind." So why is the Bush administration letting one of the world's most notorious terrorists stroll freely around the United States?

I'm talking about a man who was — until 9/11 — perhaps the most successful terrorist in the Western Hemisphere. He's believed to have masterminded a 1976 plot to blow up a civilian airliner, killing all 73 people on board, including teenage members of Cuba's national fencing team. He's admitted to pulling off a series of 1997 bombings aimed at tourist hotels and nightspots. Today, he's living illegally in the United States, but senior members of the Bush administration — the very guys who declared war on terror just a few short years ago — don't seem terribly bothered.

I'm talking about Luis Posada Carriles. That's not a household name for most U.S. citizens, but for many in Latin America, Posada is as reviled as Osama bin Laden is in the United States.
