Why “pacify” Fallujah?

A couple of weeks ago, four American missionaries were killed in Mosul. Then, on March 28, a Briton and a Canadian mercenary were killed in Mosul.

After 4 mercenaries were killed in Fallujah, Kimmitt goes all ballistic and vows revenge and says he’s going to “pacify” Fallujah.

Isn’t this a little…inconsistent? Is it the Mogadishu-like desecration that got the American military all riled up? But that has happened before. In Mosul.
