TEHRAN -- Iran's delight at the U.S. military exit from Afghanistan has given way to dilemmas over how to handle the Taliban regime and the prospect of increased terrorist activity both in the central Asia country and Iraq.
Tehran also faces a struggle to protect trade and investment interests in Afghanistan, as rival powers including Pakistan, Turkey and Qatar offer help to the new rulers in Kabul to win regional influence. The conundrum that faces Washington's bitter enemies in Iran shows the complex and still evolving fallout of the U.S. military's Afghan retreat on the power politics of the wider region.
