Might as well say it: the United States is at war in Yemen. The administration would prefer we didn't notice this, but it is true. Listen to Noah Shachtman and Spencer Ackerman at Wired's Danger Room:
These authors dig into developing U.S. operations in Yemen and produce considerable evidence that we're slipping more and more deeply into yet another country's civil war.
Ibrahim Mothana tried to get across what is happening in that strategically located ancient country in an oped in the New York Times:
I'm old fashioned. I think when a President leads this country into a faraway war that will cause yet another population to hate us, he ought to tell us about it. Did not the Constitution say something about Congress declaring wars? How quaint.
Several sources recommend Waq al-Waq written by Gregory Johnsen, a Princeton scholar, for on-going English coverage of our Yemen war. Just in case we notice that we've poked another hornet's nest.
