Israel conducted its own parallel campaign under the code name Operation Roaring Lion, which Israeli officials described as the largest operational strike sortie in the Israeli Air Force's history, involving roughly 200 warplanes and about 500 objectives .

The opening salvo killed several top Iranian officials, including Supreme Leader Ali Khamenei, and triggered a massive Iranian retaliatory barrage of hundreds of missiles and thousands of drones — a response Iran dubbed Operation True Promise IV . Within the first ten days alone, the U.S. and Israel collectively struck over 15,000 Iranian targets, with Iran's missile launches declining by 90 percent and its drone attacks falling by 80 percent according to a March 13 Pentagon briefing .

Secretary of State Marco Rubio declared on May 5, 2026, that Operation Epic Fury had concluded because its objectives had been achieved, and that Washington now preferred "the path of peace" . Britannica also records the operation as ending on May 5 .

The Vance-Rubio Policy Divide

By late June 2026 — after a preliminary U.S.-Iran memorandum of understanding had been signed — a clear rhetorical split emerged between Vice President JD Vance and Secretary of State Marco Rubio .

JD Vance's position: Vance went on a media blitz defending the peace agreement with Iran, describing it as "good progress" and stressing that a "verifiable framework" was in place for a final deal . He publicly criticized Israeli strikes on Hezbollah targets in Beirut, calling reported civilian casualties "unacceptable" and warning that further escalation could undermine ongoing diplomatic efforts — signaling that Israeli actions were threatening the fragile peace effort .

Marco Rubio's position: Rubio maintained that Israel has the right to defend itself and continued working to seal a separate agreement between Israel and Lebanon to clamp down on Hezbollah and allow Israeli withdrawal from Southern Lebanon . He was more hawkish and less willing to criticize Israeli operations, instead railing against the Iranian government .

Root of the split: The two officials come from competing Republican foreign policy camps — Vance from the skeptical, restraint-oriented wing, and Rubio from the interventionist, pro-Israel establishment wing . The divide also reflects early jockeying for the 2028 Republican presidential nomination, with Vance holding a lead in GOP primary polls but remaining conspicuously muted on the war itself during the active conflict .

Status Five Months Later (as of early August 2026)

• Combat operations ended, diplomacy fragile: The major military campaign has concluded, and a preliminary U.S.-Iran MoU is in place . However, the diplomatic framework is under strain, with internal administration disagreements complicating further negotiations.
• Ongoing tensions over Lebanon and Hezbollah: Rubio continues to push an Israeli-Lebanese agreement to neutralize Hezbollah, while Vance has signaled impatience with continued Israeli strikes, creating a contradictory U.S. posture . The Atlantic reported that the U.S. is now negotiating over one country on two different tracks — led by two men with significantly different styles and worldviews .
• Unresolved regional security issues: Iran's initial retaliatory barrage subsided after the MoU, but the long-term status of Iran's nuclear program, the fate of Hezbollah, and the stability of the Strait of Hormuz remain unresolved . The campaign and its aftermath have left thousands dead, millions displaced, and enormous damage across Iran, Lebanon, Israel, and the Gulf Arab states .
• Internal U.S. political implications: The war and its aftermath have sharpened the 2028 GOP contest. Vance, despite his early reticence, has positioned himself as the peace candidate, while Rubio has aligned himself with the hawkish national-security wing of the party . Behind the scenes, President Trump acknowledged that Vance was "maybe less enthusiastic" about the conflict, creating an opening for Rubio to emerge as one of the war's most prominent public defenders .

Where Things Stand

The U.S.-Israeli war on Iran achieved its immediate military objectives in a remarkably short timeframe, but the diplomatic and political aftermath is proving far more complex. The administration is now managing a contradictory policy — with Vance pursuing a détente with Tehran while Rubio works to limit Iran's influence through alliances with Israel and Gulf states. These competing approaches, combined with the unresolved status of Hezbollah, Iran's nuclear ambitions, and critical global shipping lanes, mean the region remains volatile. For observers, the Vance-Rubio divide is not just a Washington power struggle but a window into two fundamentally different visions of American power in the Middle East.
