The One Tool That Cannot Secure the Strait

On July 16, Vice President JD Vance explained why bombing cannot secure the Strait of Hormuz.

You can bomb them, you can take away their radar, you can take away some of their drones and some of their missiles, but it’s just too easy to fire at ships in the straits. — JD Vance

On July 31, President Trump announced that bombing Iranian infrastructure is precisely how the United States will secure the Strait of Hormuz.

From this point forward, any time the Islamic Republic of Iran shoots at a ship in the Strait of Hormuz, whether it be by Missile, Rocket, Drone, or any other device or weapon, the United States will bomb and destroy ONE BRIDGE OR POWER PLANT, including those located next to, or in, the Capital City of Tehran. — Donald Trump

Two statements, two weeks apart. The second builds a deterrent from the exact tool the first ruled out. The energy-infrastructure targeting itself is not new. The US struck Iranian bridges and rail lines in February and the South Pars Gas Field — which supplies roughly 70% of Iran's domestic gas — on February 28 in Operation Epic Fury ^[1][2]. Iran retaliated by hitting GCC desalination and power plants and Qatar's Ras Laffan LNG facility ^[3]. The IRGC framed it as an energy war from the start.

What is new is the 1:1 formula — a specific, named linkage between each ship attack and a piece of Iranian infrastructure. And it arrives under three constraints that compound the contradiction at its center. First, the air campaign the formula depends on is running thin. US interceptor stockpiles are severely depleted: Patriot inventories have dropped roughly 65%, from over 2,300 to between 759 and 827, and THAAD interceptors are down 38% ^[4]. The Center for Strategic and International Studies warned that the depletion carries operational consequences.

Diminished stockpiles may force the United States and its coalition partners to take more risks with interceptions. — Centre for Strategic and International Studies

Trump has denied any shortage.

We have far more munitions than anyone in the world, and far more than we need — Donald Trump

But in the same week he requested $67 billion in supplemental funding and told aides he wanted "more sophisticated equipment" ^[4]. The denial and the request happened simultaneously. Second, the doctrine is being deployed with the narrowest possible congressional authorization. On July 31, the same day Trump announced the formula, the Senate preserved his war powers by a single vote — 50 to 49 ^[5]. The House had already passed a war powers resolution opposing the war ^[6]. Public support for the conflict has dropped to roughly one in three Americans, and Trump told aides, "Either it goes fast or not at all" ^[6][7]. Third, the formula is not a smooth doctrinal transition. Trump halted the bombing campaign on July 24 and shifted toward diplomacy, then restarted it on July 30 after Iran continued blockading the strait ^[6]. The July 31 doctrine is a reactive restart after a five-day pause collapsed. An internal rift had surfaced just two days earlier: Defense Secretary Hegseth and Prime Minister Netanyahu pressed for more strikes, while VP Vance and General Caine warned against them ^[8]. Caine was direct.

Air power has its limits. — Dan Caine

The 1:1 formula arrived forty-eight hours after that divide broke open. The evidence that it is not deterring Iran is accumulating in real time. The IRGC responded to the July 31 escalation with an immediate counter-threat.

Hormuz daily transits remain at roughly 13, down from 45 before the conflict ^[9]. Iran's Khatam al-Anbiya command declared it "will not leave any threat or act of evil by the terrorist army of that country unanswered" ^[9]. And Iran is not merely absorbing punishment — it is rearming, purchasing 300 to 400 Chinese shoulder-fired air defense missile launchers and reportedly receiving intelligence on US bases from Beijing ^[10]. Meanwhile, the conflict has spread to a second chokepoint: Houthi militants are now blockading Saudi-linked vessels in the Bab el-Mandeb Strait, and Saudi Arabia has formed a 14-nation Maritime Defense Alliance for both the Red Sea and Hormuz ^[5]. The US Treasury sanctioned Iran's maritime insurance entities on July 29 and 30 — the Persian Gulf Marine Insurance Company and HormuzSafe Marine Services Authority — targeting the rival maritime authority Iran has built to control strait traffic ^[11]. The administration is fighting Iran's institutional control of the waterway on the financial front even as it deploys the infrastructure-strike doctrine on the military front. The vice president said bombing cannot secure the strait. The president has now made bombing the stated mechanism for securing the strait. Iran is absorbing the punishment, rearming with Chinese weapons, and vowing to punish the aggressor. The deterrent built from the one tool the administration's own leadership said cannot do the job is being demonstrated, in real time, not to do the job.
