US declares “Operation Epic Fury” over—so why are Hormuz and Iran strikes back on the table?

US officials are signaling a shift from active pressure to a posture that keeps Iran within reach. On June 3, US Secretary of State Marco Rubio told lawmakers that Washington’s military campaign against Iran, codenamed “Operation Epic Fury,” had concluded, and that any further US military action would be defensive rather than part of an ongoing offensive. Earlier the same day, US House Speaker Mike Johnson said he spent three hours at the White House with President Donald Trump and Vice President JD Vance, emphasizing Trump’s focus on reopening the Strait of Hormuz. Separately, Benjamin Netanyahu said the US and Israel could return to striking Iran if needed, framing the option as conditional rather than closed. Geopolitically, the cluster reads like a managed transition designed to reduce escalation risk while preserving deterrence. Rubio’s “campaign concluded” message is meant to constrain expectations of continued offensive operations, but Netanyahu’s statement and Johnson’s Hormuz emphasis suggest the strategic objective—securing regional energy flows and Iran’s restraint—remains active. The power dynamic is triangular: Washington sets the operational narrative to lawmakers, Israel retains battlefield leverage through its own threat signaling, and both are implicitly responding to Iran’s ability to test red lines in the Gulf. The immediate beneficiaries are US and Israeli decision-makers seeking flexibility without appearing to back down, while the likely losers are Iran’s regional deterrence posture and any actors betting on a sustained US offensive pause. Market implications center on Gulf shipping risk, energy security, and the premium investors attach to Middle East contingencies. The mention of “reopening Hormuz” points to a focus on reducing disruption risk in one of the world’s most critical chokepoints, which typically influences crude oil and refined product expectations, as well as shipping insurance and freight rates. If markets interpret “Epic Fury” as de-escalation, risk premia could ease, but Netanyahu’s “return to striking” language keeps a tail risk bid under oil-linked instruments. In practical trading terms, watch for sensitivity in Brent and WTI futures, Gulf-related shipping cost proxies, and broader risk sentiment in defense and aerospace names that track Middle East operational tempo. What to watch next is whether the US and Israel operationalize Rubio’s “defensive only” framing with concrete restraint signals, or whether Iran-related incidents trigger a rapid reversal. Key indicators include any US statements that define “defensive” actions, reported changes in US force posture in the Gulf, and real-time shipping and insurance commentary tied to Hormuz transit. On the political side, voter and policy debate around “Operation Epic Fury” after three months—highlighted by the Council on Foreign Relations piece—could pressure leaders to justify costs and outcomes, affecting how quickly escalation options are used. Trigger points for renewed strikes would likely be any Iran-linked attack on shipping, regional bases, or US/Israeli assets, while de-escalation would be signaled by sustained Hormuz normalization and the absence of retaliatory cycles over coming weeks.

Geopolitical Implications

• 01

  Washington is shifting from offensive operations to a defensive posture while keeping leverage over Iran.

• 02

  Israel’s conditional strike readiness can compress US warning time and complicate de-escalation.

• 03

  Hormuz reopening rhetoric keeps energy chokepoints central to coercive signaling.

• 04

  Domestic scrutiny of campaign outcomes may shape future use of force.

Key Signals

• —Definitions of “defensive” actions and rules of engagement.
• —US force posture changes around Hormuz and Gulf transit corridors.
• —Real shipping/insurance indicators showing whether disruption risk is easing.
• —Any Iran-linked attacks that could force a reversal to offensive options.
