The Real Threat to America: Iran May Close the Strait of Hormuz
The risk of miscalculation is now significantly higher.
The true course of any conflict is difficult to predict, but Washington should consider the possibility Iran may attempt to distract American support for Israel by threatening to close the Strait of Hormuz. By creating it crisis on the opposite end of the Middle East, Iran is not so much banking on forcing the United States to reduce support for Israel, but to overstretch its commitments, and create political and strategic costs the American people may not be willing to bear, given the generally controversial nature of the U.S.-Israeli relationship. Once more, the importance of narratives emerges—threatening Strait closure mounts pressure on the White House to find a diplomatic solution to the conflict, due to the dread and uncertainty portending a U.S.-Iran clash would conjure.
Once again, however, blockading Hormuz proves an ineffective move if the United States is willing to counter Iran’s provocations. This means Iran is more likely to respond with low-intensity, deniable warfare by utilizing cyberwarfare its deep roster of militias and terrorist groups. Be it Lebanon’s Hezbollah, Gaza’s Hamas, or Iraq’s Popular Mobilization Forces, the Ayatollah is likely to call upon these players long before seriously considering closing the Strait of Hormuz. Hezbollah, in particular, is among the most well-connected of terrorist groups in the world, possessing links with Central and South American drug cartels. A worst-case scenario would involve Hezbollah exploiting these connections to carry out terrorism on American soil. At the very least, it can be expected that Iranian-backed militias like the PMU can be used to attack U.S. and coalition forces in Iraq and Syria as the anti-ISIL campaign continues. This would force the United States/coalition to contemplate escalating their involvement in the multiple civil wars in the region, or, to their obvious detriment, refrain from retaliation.
Barring further developments, this latest threat from Tehran to close the Strait of Hormuz will likely pass without incident. It will, however, create the potential for close encounters between U.S. and Iranian naval forces in the region, leaving open a window of heightened risk of miscalculation. Furthermore, the likelihood of a war between Hezbollah and possibly Iran continues to grow by the day. If or when that war happens, the United States and the coalition will find it difficult to stay out of the line of fire.
