To my eye, the argument that the United States has a moral obligation to not abandon Afghans who want our help fighting the Taliban is quite strong.Let's see. I'd remove as inaccurate, incorrect, dishonest, and euphemistic, the following: argument, moral, obligation, abandon, Afghans, want, our, help, fighting, Taliban, quite, and strong. That leaves Yglesias' eyes, tranforming the sentiment from retarded to merely romantic.
I guess this is what remains of the edifice of Liberalism--wishy-washy imperialism masquerading as callow moral sentimentalism dressed up in the tattered, vaguely Sovietique drag of Realpolitik. "I don't think there is a strategic interest in invading and occupying foreign nations, but I do think there is compelling case for remaining in nations we've already invaded and occupied so long as there is a nebulous civil conflict in which we can pretend to take sides."
