" The IRGC is a powerful, separate branch of the Iranian armed forces. Soaked with nationalist ideology, it has grown into a state within a state in Iran, with its own naval, air and ground forces, parallel to official government institutions. The IRGC is directly controlled by Supreme Leader Ayatullah Ali Khamenei, the ultimate font of religious and political power in Iran. "

Keep that in mind when you think of the Iranian government....it is different factions fighting each other for dominance. The IRGC has seized these 15 on its own I will wager and now watch how the other factions react.
I think the cancellation of Adimanuts trip is part of the reaction of one faction.
Think about it this way...imagine a Special Operations branch of the Pentagon ...seizing 15 memebers of another countries military...on the eve of President Bush traveling to give a speech. The State Dept would have a cow...and want Bush to cancel.
This seizure is more of a slap at Adminanut and his faction than anything else.
