Falling In and Out of War

By BILL KELLER

WHEN you’ve been wrong about something as important as war, as I have, you owe yourself some hard thinking about how to avoid repeating the mistake. And if that’s true for a mere kibitzing columnist, it’s immeasurably more true for those in a position to actually start a war.

So here we are, finally, messily winding down the long war in Afghanistan and simultaneously being goaded toward new military ventures against the regimes in Syria and Iran. Being in the question-asking business, I’ve been pondering this: What are the right questions the president should ask — and we as his employers should ask — when deciding whether going to war is (a) justified and (b) worth it? Here are five, plus two caveats, and some thoughts about how all this applies to the wars before us.

1. HOW IS THIS OUR FIGHT?

It ought to be the first question we ask. Sometimes the answer is obvious. There is a broad agreement that it was in America’s vital national interest in 2001 to go after the homicidal zealots behind the 9/11 attacks on America, and the Afghan regime that hosted them. Whatever you think of how the war was waged or how long it should continue, the going-in was, as the cops say, a righteous shoot.

Often the American stake is not so clear-cut. We may feel an obligation to defend an ally. (Some allies more than others.) We have been known to fight for our economic interests. We intervene in the name of American values, an elastic rubric that can mean anything from halting a genocide to, in George W. Bush’s expansive doctrine, promoting freedom.
