obviously, the yemeni army is marching into the desert under u.s. urging/threat. but the complexity of the situation (which you can begin to understand here) should give us pause. they're dealing with a shiite rebellion. a leftist insurgency, a proxy war between saudi arabia and iran. now: where are they marching? against whom? it's not a matter of just kicking someone's ass. there are many, many ways this becomes an impossibly complex disaster.
