America Isn’t ‘Technically’ at War with Iran But America Is Still Paying the Price Day After Day

National Security Journal | Shay Bottomley

U.S. naval operations in the Strait of Hormuz continue to defend commercial shipping amidst an undeclared conflict with Iran that began in February 2026. Vice President J.D. Vance stated on September 3, 2026, during the first White House press briefing in over 40 days, that American maritime protection prevents a catastrophic global energy crisis.

Prior to February, 20% of world oil traversed the key waterway. Washington maintains that diplomatic negotiations will resume only after Iranian maritime strikes terminate completely. Strategic tension persists. The confrontation highlights how modern military actions proceed without formal congressional declarations of war, a practice absent since 1941 when President Franklin D. Roosevelt signed a declaration of war against Nazi Germany. Vice President Vance also expressed deep skepticism regarding Iranian state media claims of an alleged U.S. strike on an Iranian wedding party, confirming an active investigation while asserting American forces never target civilians.

Comment

Executing high-tempo maritime protection operations without a formal congressional declaration relies on executive authority under the War Powers Resolution of 1973. This framework provides immediate operational flexibility to deploy carrier strike groups into the Strait of Hormuz. However, sustained combat operations without legislative authorisation risk eroding congressional funding support during prolonged attrition. Strategic ambiguity grants tactical speed but exposes maritime deployments to mounting political friction in Washington.

A similar operational trade-off occurred during Operation Earnest Will in 1987, when the United States Navy escorted reflagged Kuwaiti tankers through the Persian Gulf against Iranian silkworm missiles and naval mines. Escorting commercial shipping while avoiding a formal war declaration created severe scheduling strains across Atlantic Fleet surface combatants. The operational friction during Operation Earnest Will demonstrates how prolonged Persian Gulf escort duties drain United States Navy destroyers from wider Indo-Pacific force rotations.

Strategic Question for Discussion

Which factor imposes a sharper constraint on open-ended maritime escort missions in the Strait of Hormuz — the domestic legal limitations of the War Powers Resolution of 1973, or the fleet readiness costs demonstrated during Operation Earnest Will?

The historical precedent of Operation Earnest Will suggests that material readiness constraints ultimately bind operational commanders faster than statutory mechanisms like the War Powers Resolution of 1973. While executive authority allows rapid initial naval deployments into the Strait of Hormuz, continuous maintenance and surface combatant rotation requirements inevitably force a choice between mission scaling and global fleet commitments. Sustainment bottlenecks and vessel availability are likely to dictate the operational timeline long before congressional intervention occurs.
