It appears that once again, the Iranian regime is playing a familiar game of geopolitical chicken in the Strait of Hormuz. Known for their attempts to blackmail the West by threatening one of the world’s most vital maritime routes, this time they might have bitten off more than they can chew. After all, Iran’s navy and air force have seen better days—specifically before they were “taken care of” by the United States. The real question isn’t whether Iran can close the Strait, but rather how long it can keep up the charade in the face of mounting pressure.

While Iran’s Supreme Leader issues threats from his disjointed and faction-riddled regime, President Trump and his administration aren’t exactly quaking in their boots. The Iranians may enjoy pretending they’re still a force to be reckoned with, but in truth, they seem more like that neighborhood dog that barks at everyone as they pass by but would tremble if anyone stopped to say hello. With no navy, no significant air force, and leaders who can’t seem to find the same page let alone read from it, Iran’s aggressive posturing appears more desperate than dangerous.

Of course, the nuisance of small boats causing problems in the Strait is a fly in the ointment for international shipping. These fiberglass speedboats, likened to decked-out Boston Whalers with machine guns, may try to cause a stir, but it’s hard to be truly intimidated by what are essentially floating gnats. While they might be able to harass shipping traffic, they’re about as likely to seriously threaten U.S. forces as a slingshot is to a tank. The U.S. Navy, along with thousands of ready-and-waiting Marines, are setting a tone that’s more “No nonsense” than “diplomacy as usual.”

However, amidst the bluff and bluster, a serious operation is underway. Mine countermeasure assets continue to be employed in a methodical process of sweeping and clearing the Strait, ensuring the waterway remains open for business. With ships en route from as far as Japan, it’s clear that not only do the U.S. forces have the capability but also the resolve to ensure that Iran’s attempt to be the regional gatekeeper is mostly wishful thinking. No mines have been found yet, but that doesn’t mean vigilance gets a day off.

So, while Iran’s leaders are busy blowing hot air, spreading confusion about their capabilities, U.S. forces are busy putting out fires—metaphorically-speaking—before they even start. As former Navy Lieutenant Commander Tom Sour noted, the Iranians can’t seem to unify under any single voice of reason. While a game of geopolitical chess plays out in the Middle East, it’s clear that the United States is playing with a full board while Iran fumbles around, trying to figure out what exactly its next move might be.
