I don't think it matters what the US decides to do here. It's a lost cause either way. If the last failed war in Afghanistan (and Vietnam) taught us anything, it's that native bootstrapped insurgency is impossible to stop, as long as it's cheap and persistent enough and can keep the recruits coming. Yemen's Houthis are arguably gaining even more popular support than the Taliban ever had, across the entire Muslim world, Sunni and Shia united. The fact that the US's closest allies, even Saudi Arabia who had previously fought the Houthis for years, are refusing to cooperate publicly on this one, is a sign of the massive popular support that the Houthis enjoy. They'll have no trouble refilling their ranks. Also doesn't help that they have an indirect line to Russian military manufacturing via Iran.
