I've registered as a Republican exactly once in my life. The year was 1980, and Ronald Reagan, who died today at the age of 93, was seeking the GOP nomination for president. Teddy Kennedy was challenging President Jimmy Carter for the Democratic nomination, and in Massachusetts, where I then lived, Kennedy was certain to win the primary. Better to cast my vote where it could do some good—in favor of John Anderson, who at that point was running as a Republican, and who seemed the only candidate capable of denying Reagan the nomination. Reagan was dangerous. He wanted to eliminate vast portions of the government indiscriminately, and he wanted to commit the military to ill-considered interventions abroad.

But the only hot war waged during the Reagan administration was to remove a comic-opera Marxist government from the tiny Caribbean island of Grenada. The United States retreated from Lebanon after a suicide bomber killed more than 200 American soldiers. It is seldom observed that Saddam's gassing of the Kurds, which George W. Bush rightly denounced prior to the Iraq war, occurred on Reagan's watch. In 1984, when the Reagan administration got its first inkling that Iraq was engaged in chemical warfare, it chose not to make a fuss. The most ambitious foreign intervention during the Reagan administration--the funnelling of aid to the Nicaraguan contras--was done illegally, and, after it was discovered, embroiled Reagan's second term in a scandal from which it never recovered.
Reagan can probably claim some credit for ending the Cold War, but his principal weapon, characteristically, was spending—the Soviets bankrupted themselves trying to keep up with the Pentagon's weapons-buying binge through the 1980s. Reagan's greatest achievement in foreign affairs was therefore linked to his greatest achievement in domestic affairs. He taught Republicans that they could be even less responsible than Democrats.
