A major success in Iraq
One of the most brutal men in the world has met his end. Abu Musab al-Zarqawi is dead. If it's a victory for the Coalition troops, it's also a victory for the Iraqi people, who have had to deal with this thug as much as anyone.
Opinions on the significance of his death are varied. But there are a few worth looking at:
Iraqi Prime Minister Nuri al-Maliki:
"Every time a Zarqawi appears we will kill him."

Rohan Gunaratna, Institute of Defense and Strategic Studies in Singapore
"If that information is true, it is the most significant victory in the fight against terrorism. He was certainly the most active terrorist in Iraq. More than that, he was using Iraq to mount operations in the neighborhood, for instance the Jordan attacks [last year] were by his group...
"He had an extensive network overseas, in Europe and in the Middle East, and he was expanding this network...
"Zarqawi didn't have a No. 2. I can't think of any single person who would succeed Zarqawi...In terms of effectiveness, there was no single leader in Iraq who could match his ruthlessness and his determination. It will be very difficult to replace a man of the stature of Zarqawi."

Let's hope.
