U.S. Sends More Troops Despite “Endgame” Talk — Even as the White House signals the war with Iran may be nearing its conclusion, the Pentagon is surging thousands of additional troops into the region. We break down what this buildup really means—and how it’s designed to pressure Tehran at the negotiating table while preparing for escalation if talks collapse.
North Korea’s Nuclear Program Speeds Up — New warnings from the International Atomic Energy Agency suggest Pyongyang is expanding its uranium enrichment capabilities, potentially allowing Kim Jong Un to grow his nuclear arsenal faster—and with far less visibility to the outside world.
