The Houthis picked this fight, raining nearly 90 missiles and drones on Mokha's port, shutting it down and killing workers who never held a weapon. Now an offensive aimed at Bab al-Mandab has pushed the death toll past 300 and driven roughly 1,800 families from their homes in Taiz. The era of attacking without paying a price has to end, and Yemen's government is right to hit back hard.
