Washington Is Preparing to Outlast Tehran
The United States is signaling that its confrontation with Iran may be entering a different phase: fewer dramatic airstrikes, but potentially a much longer economic and maritime siege.
Defense Secretary Pete Hegseth said Washington can maintain its naval blockade of Iran “indefinitely” by rotating US warships through the region. Treasury Secretary Scott Bessent, meanwhile, has promised additional economic measures against Tehran, while President Donald Trump says Iran will face increasingly severe financial pressure if it refuses to compromise.
Vice President JD Vance has also offered one of the clearest descriptions yet of Washington’s priorities. He put keeping American oil and gasoline prices under control first, followed by preventing Iran from obtaining a nuclear weapon.
That language matters.
Six months into the war, the administration’s emphasis is moving away from achieving a spectacular military conclusion and toward creating conditions Washington believes it can sustain longer than Tehran.
The blockade sits at the center of that strategy.
Iran needs access to international markets, shipping, foreign currency and energy exports. Washington appears to believe that restricting those flows—while preserving the ability to strike again—can impose greater cumulative pressure than another expensive bombing campaign.
Hegseth’s claim that the blockade can continue indefinitely is therefore intended as psychological warfare as much as military policy.
The message to Tehran is simple: America does not need to invade Iran to exhaust it.
But endurance cuts both ways.
Maintaining a major naval force around Iran requires ships, crews, maintenance, air-defense systems and continuous logistics. The USS George Washington is already moving toward the Middle East as Washington prepares to rotate the long-deployed USS Abraham Lincoln, illustrating the strain created by prolonged operations.
Iran, meanwhile, is trying to make the blockade expensive for Washington and politically painful for its allies.
Traffic through the Strait of Hormuz has again slowed sharply after attacks on commercial vessels. Before the war, more than 130 ships could transit the waterway daily; current traffic has fallen to only a fraction of normal levels. The strait historically carried roughly one-fifth of global oil and LNG shipments.
That gives Tehran its own endurance strategy.
Iran does not have to defeat the US Navy. It needs to keep enough uncertainty around Hormuz to raise insurance costs, disrupt energy flows and push fuel prices higher in countries far from the battlefield.
This is why Trump’s domestic economic objective matters strategically.
If American voters begin feeling the Iran war every time they fill their cars, Tehran gains leverage without winning a conventional battle.
Washington therefore wants to isolate Iran economically while preventing Iran from successfully exporting economic pain to the United States.
The confrontation is becoming a contest over who breaks first.
The same dynamic is spreading toward Yemen. Houthi forces have renewed attacks against Yemeni government positions and maritime targets around the Red Sea. The latest strike on Mokha reportedly killed civilians and hit commercial vessels, demonstrating how easily pressure around Hormuz can be supplemented by instability around Bab el-Mandeb. Reuters also reported renewed Houthi attacks on the Yemeni government-held port city.
For Washington, this creates the nightmare of a two-chokepoint war.
Hormuz threatens Gulf energy exports.
Bab el-Mandeb threatens the alternative Red Sea route.
Iran and its regional partners do not need to close either waterway completely. Persistent insecurity may be enough to impose global economic costs.
WARYATV ASSESSMENT
Trump appears to be changing the theory of victory.
Earlier phases of the war emphasized overwhelming military power: destroying Iranian infrastructure, degrading missiles and preventing nuclear breakout.
The emerging strategy looks different.
Contain Iran’s nuclear capability. Keep American energy prices manageable. Maintain the naval blockade. Intensify sanctions. Wait for Tehran’s economic position to deteriorate.
That is no longer a short war.
It is a war of endurance.
Iran believes time can weaken American political resolve.
Trump believes economic isolation can weaken Iran faster.
Neither side currently appears willing to concede.
The danger is that an “indefinite” blockade can also produce an indefinite conflict—one that consumes American military resources, keeps Hormuz unstable and provides Houthis and Iraqi militias with repeated opportunities to widen the battlefield.
Washington may have concluded that it does not need another massive bombing campaign to defeat Tehran.
But if the strategy becomes permanent economic warfare without a political settlement, the United States could discover that maintaining pressure is easier than converting pressure into peace.
The Iran war is therefore entering its most consequential phase.
The question is no longer who can strike harder.
It is who can endure longer without breaking first.
