As predicted here, it is up fast and down fast for the ISIS, the Islamic State of Iraq and Syria, also known as ISIL, the Islamic State of Iraq and the Levant, terrorists. Strategy Page continues to provide the best coverage of events in Iraq on the net:
August 19, 2014: Kurdish troops have forced ISIL (al Qaeda in Iraq and the Levant) fighters out of the Mosul Dam on the Tigris River. ISIL seized control of the dam on August 3 rd. This is the largest dam in Iraq and because of shoddy construction during the 1980s requires constant maintenance to prevent it from failing. If the dam did come down over half a million Iraqis could die from the flood and subsequent water shortages. The Kurds had been defending the dam since the Iraqi Army ran away in early June. ISIL also seized two nearby Kurdish held towns as they went after the dam.
This ISIL advance was not unexpected because the Kurds stretched themselves thin by trying to replace the Iraqi Army while also building and defending a new fortified border to incorporate Kirkuk and nearby oilfields. The Kurds asked for air support from the United States but did not start receiving it until the 8th. The Americans had already shipped in ammo and light weapons and some additional American trainers and advisors.
ISIL hit the Kurds with multiple columns of vehicles carrying armed men. This force included some suicide bombers and there were more ISIL gunmen coming from more directions than the small Kurdish force could handle. After a day or so of holding off ISIL the Kurds were ordered to withdraw and they did that in an orderly fashion on the 3rd. The Kurds organized a counterattack force and moved to regain the lost territory once the U.S. agreed to resume air support. There are still some ISIL gunmen in the vicinity of the dam, as well as some mines and booby-traps the Islamic terrorists set before they left. Kurdish forces are taking care of this.
In the Euphrates River Valley, near the town of Haditha, local Sunni tribes have rebelled against ISIL to maintain control of another major dam. This is a major setback for ISIL, which expected the Sunni tribes to support them and take care of local security. It’s an old story being replayed. The local tribesmen are not happy with ISIL efforts to force a strict Islamic lifestyle on them. Iraqi and Syria Sunnis have come to prefer educating their daughters and enjoying TV and videos. There is even more tolerance for buying alcoholic beverages from local Christians who have long been allowed to sell this stuff because their religion does not forbid it (and their worship services actually use wine). Also unpopular is the ISIL attitude that anything they do is above reproach. The Sunni tribes that ISIL expected to be allies and take care of administering the newly conquered territories have increasingly refused to go along. While the Sunni tribes like the measure of law and order ISIL has imposed they are not willing to accept all the other features of ISIL rule. The secular Sunnis (mainly the surviving Baath Party organizations) initially believed they could work with ISIL but have since turned against the strict forms of Islam ISIL insists on. Meanwhile ISIL has antagonized many Islamic conservative groups by destroying shrines and even mosques ISIL considers heretical despite the fact that most Sunni Arabs tolerate these places because they are very popular, and bring in a significant amount of tourist business from foreigners and religious pilgrims.
