There’s a classic thought experiment in game theory called the game of chicken. Two drivers race toward each other on a narrow road. The first to swerve is the “chicken” — the loser. But if neither swerves, both crash. The whole thing works because each driver is convinced the other will back down first. The moment both of them believe that simultaneously, the crash becomes inevitable.
That is, more or less, the situation in the Strait of Hormuz right now. And the car wreck, in this case, costs the world economy billions of dollars every week.
Here’s the basic structure of the standoff. Iran closed the Strait of Hormuz after the US-Israeli strikes in late February, blocking the waterway through which roughly 20% of the world’s oil normally flows. In mid-April, the US responded by imposing its own blockade on Iranian ports. Now each side has essentially locked the other out. Iran’s position: the blockade on its ports must end before it reopens the strait. The US position: the strait must reopen before any concessions are made. A conditional ceasefire has been in place since April 8, but the strait remains effectively closed — and both Washington and Tehran are sitting at the table in Islamabad through Pakistani mediation while refusing to move on the core issue.
What makes this more than just a military standoff is the asymmetry in how much each side needs a resolution. For Iran, this conflict is existential — its nuclear program, its deterrence strategy, its regional influence are all on the table. An Iranian official said publicly: “We fight, we die, but we don’t accept humiliation. Surrender is fundamentally incompatible with Iran’s identity.” Whether you agree with that position or not, it signals something strategically important: Iran’s leadership believes it can absorb pain longer than the US can politically. For Washington, the conflict is serious but not existential. Americans are experiencing higher gas prices, stock market turbulence, and economic uncertainty — and crucially, midterm elections are on the horizon. Tehran is betting that democratic politics will eventually force Trump’s hand before Iranian resolve breaks.
This is a classic game theory problem known as the war of attrition. Both sides are willing to keep fighting as long as they believe the cost to the other side is higher than the cost to themselves. The side that miscalculates loses. And here’s what makes it genuinely dangerous: both sides think they’re winning the calculation. Iran has watched weeks of US and Israeli strikes fail to break its will, which has actually reinforced its belief that endurance is its greatest strategic asset. The US, for its part, is watching Iran’s economy deteriorate further under the combined pressure of a blockade on top of years of sanctions, and believes time favors Washington. The result, as analysts at CSIS put it, is a “paradoxical equilibrium” — a situation where neither side is strong enough to force the other’s hand, but neither side is weak enough to concede.
The most revealing moment in this standoff came in March, when Trump posted that there would be “no deal with Iran except UNCONDITIONAL SURRENDER.” Iran’s supreme national security council replied by ruling out negotiations entirely. Both statements were almost certainly exaggerated for domestic audiences — Trump’s base wants toughness, and Iran’s government needs to project strength domestically — but they also made the next round of genuine talks harder to start. That’s another game theory concept at play: costly signaling. When you publicly declare a maximalist position, backing down later has a reputational cost. Both sides have now staked out positions that make compromise politically expensive, which is part of why even the Islamabad talks in April ended without a breakthrough.
What actually reopens the strait, if it ever does, probably won’t be a dramatic military victory by either side. It’ll be a face-saving diplomatic construction that lets both governments claim they didn’t blink — a formula where Iran gets something on sanctions or frozen assets, the US gets something on nuclear terms, and both announce it as a win. That’s how most coercive standoffs end, not with one side defeated, but with a negotiated ambiguity that each side sells differently to its own people. The problem is getting there. As long as both sides are focused on breaking the other’s will rather than building a deal, the strait stays closed, oil stays expensive, and the global economy keeps absorbing the cost of two governments playing chicken with the world’s energy supply. The real loser in a game of chicken isn’t the one who swerves. It’s everyone watching from the side of the road.
