I have a new piece in Foreign Policy on the slow, but real, militarization of the Caspian Sea:
While the world focuses on the possibility of an Israeli attack on Iran, a little-noticed arms buildup has been taking place to Iran's north, among the ex-Soviet states bordering the Caspian. Twenty years after the collapse of the Soviet Union created three new states on the sea, their boundaries have still not been delineated. And with rich oil and natural gas fields in those contested waters, the new countries -- Azerbaijan, Kazakhstan, and Turkmenistan -- are using their newfound riches to protect the source of that wealth. So they're building new navies from scratch, while the two bigger powers, Russia and Iran, are strengthening the navies they already have. It all amounts to something that has never before been seen on the Caspian: an arms race.
