Iran trying to fill American vacuum...

This is very dangerous....

Iran is moving to cement ties with the leaders of three key American allies—Afghanistan, Pakistan and Iraq—highlighting Tehran's efforts to take a greater role in the region as the U.S. military pulls out troops.

The Afghan and Pakistani presidents, visiting Tehran, discussed with Iranian President Mahmoud Ahmadinejad "many issues…that might come up after the NATO military force goes out of Afghanistan," Iranian Foreign Minister Ali Akbar Salehi said in an interview here Sunday.

"The three presidents were very forthcoming in carrying out the cooperation and contacts so as to make sure things will go as smoothly as it could," he said.

That was a jab at Washington, which is increasingly in competition with Tehran for influence in the region, particularly as popular rebellions have surged across the Middle East and North Africa since January.

The overtures by U.S. nemesis Iran come amid tensions between Washington and three governments that have each received billions of dollars in U.S. aid. Afghan President Hamid Karzai, before traveling to Tehran, welcomed President Barack Obama's announcement on Wednesday that the U.S. would withdraw 33,000 U.S. troops from Afghanistan over 15 months.
