how is the world after Imad Mugniyah?!

For sure a better place! Any element that IRGC protect or sponsor is a source of fanatic radicalism which just brings death, terror and misery so elimination of any of these elements will make world better place to live.

I am confused a little here; probably someone could help me out here. We know that IRGC has supported terrorism and has funded Islamic Jihad movement in Shiite section of Muslim world right after Iranian revolution and according nytimes "Mugniyah, who was killed Tuesday in a car bombing in Damascus, Syria, was the leader of the Islamic Jihad Organization. He was at the violent center of the Shiite group Hezbollah, acting under the auspices of radical Iranian sponsors, according to Western authorities and terrorism experts.

He is thought to have moved frequently between Beirut, Lebanon, Damascus and Tehran. His expertise and his protection by the leaders of Hezbollah in Lebanon and the Revolutionary Guards Corps in Iran made him hard to capture or to kill, according to intelligence experts. He was considered an agent of a wing of the Revolutionary Guards, which the United States says has sponsored terrorist attacks around the world since the Iranian revolution."

Also as you know of the US put IRGC in the foreign terrorist organizations list just in 2007. The question is, we have had huge amount of intelligence about IRGC and their activities, why didn't the US put it in the foreign terrorist organizations list much earlier?!
