Naval incidents in the Gulf have spotlighted the danger that a U.S.-Iranian skirmish could blow up into war. The two sides have little ability to communicate at present. They should hasten to design a military-to-military channel to lower the chances of inadvertent conflagration.

What’s new? Tensions between the U.S. and Iran have repeatedly brought the two sides to the brink of open conflict. While neither government seeks a full-fledged war, a string of dangerous tit-for-tat exchanges amid mounting hostile rhetoric underscores the potential for a bigger military clash.

Why does it matter? Due to limited communication channels between Tehran and Washington, an inadvertent or accidental interaction between the two sides could quickly escalate into a broader confrontation. The risk is especially high in the Gulf, where U.S. and Iranian military vessels operate close to one another.

What should be done? The U.S. and Iran should open a military de-escalation channel that fills the gap between ad hoc naval communications and high-level diplomacy at moments of acute crisis. A mechanism facilitated by a third party might contain the risk of conflict due to misread signals and miscalculation.
