Now that NATO has shot down an Iranian missile aimed at Incirlik Air Base in Turkey and an American submarine torpedoed an Iranian frigate off the coast of Sri Lanka, the conflict with Iran extends from the skies above NATO to the Indian Ocean floor. The Iranians are not just attacking U.S. and Israeli bases, but also civilian targets across the Middle East and neutral shipping in the Persian Gulf. As the battlefield widens, oil prices begin to climb, and the stock market starts to wobble, many onlookers are growing nervous about the prospects of a quick conclusion to this war or even of an American victory.
