While the terrorist violence is still down 90 percent from its 2007 peaks, there has not been much additional reduction. Each month, 200-300 people die from terrorist activity. Most of this mayhem is from Sunni Arab nationalists (both secular and religious), who are determined to return Sunni Arabs to power, or die trying. So the dying will continue until these fanatics are all dead. This could take years. It’s mainly a generational thing. The few older terrorists left have access to enough money, and younger sons and nephews (who tend to be uneducated and unemployed) that they can get bombs made and placed. Suicide bombers are harder to come by, which is the main reason there are fewer attacks. There is also less and less cash for this stuff. Corrupt terrorist leaders stole a lot of that money (part of the billions Saddam and his cronies stole from Iraq’s oil revenue over the years) and there’s simply been less and less of it each year. What there has been more and more of each year are trials, convictions and executions of senior terrorist leaders. There are also more incidents of terrorist leaders being found, refusing to surrender, and dying in the ensuing gun battle. All this sends a message, that this is the end. According to police interrogations, this had been bad for terrorist morale.
