Yemen's Houthis imposing a blockade on Saudi Red Sea ports signals a dangerous escalation in the war on Iran.

The author criticizes Trump's return to war, seeing it as a squandered opportunity and a route to an unwinnable conflict, urging diplomacy and an immediate ceasefire to avert further pain.
