The U.S. Senate moves to curb presidential war powers as the Trump administration maintains a dual-track policy of military threats and active diplomacy.

In a significant political shift, the U.S. Senate voted 50–47 to advance a war powers resolution aimed at limiting President Trump’s ability to conduct military operations against Iran without congressional approval. The measure saw a rare break in GOP unity, with Senator Bill Cassidy joining three other Republicans to support the resolution. While the White House continues to signal a willingness to negotiate, Vice President JD Vance emphasized that U.S. forces remain 'locked and loaded' for further confrontation, asserting that the administration is pursuing a policy that avoids a 'forever war.' On the maritime front, tensions have escalated following the reported U.S. seizure of the oil tanker 'Skywave' in the Indian Ocean. The vessel, which was sanctioned in March, is believed to have loaded over a million barrels of Iranian crude. Simultaneously, Iran's Islamic Revolutionary Guard Corps (IRGC) has reportedly expanded its pressure tactics to digital infrastructure, threatening to charge 'protection fees' for the maintenance of subsea communications cables in the Strait of Hormuz. The regional conflict is also seeing mounting environmental and humanitarian costs. Recent reports indicate that a strike on an Iranian oil refinery resulted in a significant oil spill that has reached a protected wildlife sanctuary in the Persian Gulf. Despite these developments and the ongoing U.S. maritime enforcement campaign, Tehran maintains a hardline stance, signaling readiness for further retaliation and continuing its efforts to disrupt shipping lanes in the Strait.
