What should Congress do?

To his dovish base, Obama insists on how limited and militarily marginal the strike will be. To undecided hawks such as Sens. John McCain and Lindsey Graham, who are prepared to support a policy that would really alter the course of the civil war, he vaguely promises the opposite — to degrade Assad’s military while upgrading that of the resistance.

Problem is, Obama promised U.S. weaponry three months ago and not a rifle has arrived. This time around, what seems in the making is a mere pinprick, designed to be, one U.S. official told the Los Angeles Times, “just muscular enough not to get mocked.”

That’s why Dempsey is so glum. That’s why U.S. allies are so stunned. There’s no strategy, no purpose here other than helping Obama escape self-inflicted humiliation.

This is deeply unserious. Unless Obama can show the country that his don’t-mock-me airstrike is, in fact, part of a serious strategic plan, Congress should vote no.
