[National Interest] However, it goes much deeper than that--namely, while Iran's military is greatly inferior to the U.S. armed forces, the U.S. military would not be able to conquer Iran swiftly and cheaply like it did in Iraq and Afghanistan. In fact, Tehran would be able to impose prohibitive costs against the U.S. military, even before the difficult occupation began.
Iran's ability to defend itself against a U.S. invasion begins with its formidable geography. As Stratfor, a private intelligence firm, has explained, "Iran is a fortress. Surrounded on three sides by mountains and on the fourth by the ocean, with a wasteland at its center, Iran is extremely difficult to conquer."
While the "stopping power of water" has always made land invasions far more preferable for the invading party, the age of precision-guided munitions has made amphibious invasions particularly challenging. As such, the United States would strongly prefer to invade Iran through one of its land borders, just as it did when it invading Iraq in 2003.
Unfortunately, there are few options in this regard. On first glance, commencing an invasion from western Afghanistan would seem the most plausible route, given that the U.S. military already has troops stationed in that country. Alas, that would not be much of an option at all. |
