Iran Sends Arms to Iraq, Afghanistan

At Wall Street Journal, "Iran Funnels New Weapons to Iraq and Afghanistan."
TEHRAN—Iran's elite military unit, the Islamic Revolutionary Guard Corps, has transferred lethal new munitions to its allies in Iraq and Afghanistan in recent months, according to senior U.S. officials, in a bid to accelerate the U.S. withdrawals from these countries.

The Revolutionary Guard has smuggled rocket-assisted exploding projectiles to its militia allies in Iraq, weapons that have already resulted in the deaths of American troops, defense officials said. They said Iranians have also given long-range rockets to the Taliban in Afghanistan, increasing the insurgents' ability to hit U.S. and other coalition positions from a safer distance.

Such arms shipments would escalate the shadow competition for influence playing out between Tehran and Washington across the Middle East and North Africa, fueled by U.S. preparations to draw down forces from two wars and the political rebellions that are sweeping the region.

The U.S. is wrestling with the aftermath of uprisings against longtime Arab allies from Tunisia to Bahrain, and trying to leave behind stable, friendly governments in Afghanistan and Iraq. Iran appears to be trying to gain political ground amid the turmoil and to make the U.S. withdrawals as quick and painful as possible.

This is classic international politics. I'm reminded of how the Soviet Union saw an improvement in the world correlation of forces after the American withdrawal from Vietnam. By the late-1970s the shift of influence and momentum in the Third World had shifted to Moscow. Iran can't operate on a global scale as the Soviets did, but most of the important developments in national security right now are in the Middle East and South Asia. And given how poorly the Obama administration has responded to current events, Egypt's revolution for example, and the political cut-and-run from Afghanistan, things aren't likely to improve a whole lot in the short term.
