Tehran, while not trying to create an empire of sorts throughout the Middle East, as some have offered, certainly seems focused on expanding its regional interests and influence—as any power on the rise would naturally seek to do. The natural defense of such interests could, by default, turn Iran into the Middle East’s new regional hegemon. Look far and wide into the soul of U.S. diplomats, and that is the real fear (and a shared one among Washington’s allies in the region). While many in the Middle East and beyond fear Iran’s possible nuclear aspirations, such weapons are only a part of a much bigger geostrategic challenge.
The facts are simple: Washington and Tehran are locked into a long-term geopolitical contest throughout the Middle East that will span decades—a similar contest in many ways to Washington and Beijing’s battle for influence in the Asia-Pacific and wider Indo-Pacific regions.
Over the long term, the U.S.-Iranian struggle throughout the Middle East could very well be a mini-Thucydides trap, to steal the phrase from my beloved Harvard’s resident geostrategic guru, Graham Allison—the classic tale of how when a rising power meets an established power, war is oftentimes the most common result (eleven out of fifteen times, per Allison).
