Costs of Iran deal piling up

When Iranian Brig. Gen. Hossein Hamedani was killed last Thursday advising Syrian government forces fighting to regain control of the city of Aleppo, he was publicly mourned by no less than the nation's supreme leader, Ayatollah Ali Khamenei.

"Gen. Hamedani devoted the final years of his fruitful life to fight against anti-Islam Takfiris and fulfilled his martyrdom wish in the same front," Khamenei was quoted as saying.

Before coming to Syria, Hamedani was a key leader of Iran's Islamic Revolutionary Guard Corps and led the crackdown on pro-democracy protesters in 2009, an act for which he was sanctioned by the European Union.

The death in Syria of such an important figure in Iran's Shiite Muslim theocracy is one of many recent signs that the nuclear agreement reached July 14 in Vienna has not slowed Tehran's aggressive policies as the Obama administration had publicly hoped.
