(POPULAR MECHANICS) — The United States and Iran have engaged in a war of words over their military capabilities in the last few weeks. But if an actual war breaks out, it will not be a war of U.S. bombs versus Iranian bombs, but of U.S. bombs versus Iran's bunkers.
Iran's network of nuclear facilities, some of which are underground, would be the primary target of an Israeli or U.S. attack intended to destroy Iran's suspected clandestine weapons program. As the rhetoric has heated up, the United States has been talking up its military capabilities. Whether American or Israeli bombs indeed could penetrate or destroy Iranian bunkers, though, is still unclear.
