Trump Sets U.S. Military Casualties as Red Line for Resuming Full-Scale Iran War, WSJ Reports

According to the Wall Street Journal citing U.S. officials, Trump privately told staff on June 4 that he would not resume full-scale military operations against Iran unless U.S. military personnel are killed, signaling the White House's intent to maintain the fragile ceasefire and prevent further Middle East escalation.

This week marked one of the most intense exchanges since the ceasefire took effect in early April. Iran fired missiles and drones at U.S. bases in the Middle East and Kuwait International Airport, while American forces conducted retaliatory strikes. The two sides' ongoing confrontation over control of the Strait of Hormuz continues to disrupt global energy markets and international shipping. U.S. officials said Trump remains willing to tolerate limited military friction for weeks or months rather than escalate to all-out conflict, while pursuing diplomatic channels to address Iran's nuclear program.
