After three decades of festering tensions, the United States and Iran are now facing off in a full-fledged cold war.
When the first Cold War began, in 1946, Winston Churchill famously spoke of an Iron Curtain that had divided Europe. As Cold War II begins half a century later, the Bush administration is trying to drape a kind of Green Curtain dividing the Middle East between Iran's friends and foes. The new showdown may well prove to be the most enduring legacy of the Iraq conflict. The outcome will certainly shape the future of the Middle East -- not least because the administration's strategy seems so unlikely to work.
