Stay out. A Houthi strike on King Khalid airport killed at least twelve people and wounded 309, and Trump's answer is that the United States may join Saudi strikes because "we move very quickly." That's a recruitment pitch.
Count the dead. Four Saudis, two Bangladeshis, one each from the US, Jordan, Palestine, Syria, Sudan and Egypt. An Indian national died of the injuries the next day. Sunday, terminals 3 and 4: a Pakistani resident dead, eleven hurt, on the tarmac beside parked planes. Same rights, same fight. None of them own this war.
The Houthis say it answers Saudi aggression and claim more than 120 airstrikes in a day. That figure isn't confirmed. What is: they named airports as targets, this was the third hit in a week, and Guterres called it a violation of international law. Rubio says the attacks must stop and that Washington stands with the kingdom. Al-Malki wants a decisive response. More bombs don't bring anyone back.
No sign by Sunday that Trump had moved. Good. Who owns the choice to jump in? A president, and a badly sourced claim that the crown prince wants him deeper in. The sources still don't name the American who died. Don't draft a war off a body you won't identify. That's a management problem for the people already bombing, and workers in the terminal pay it.
