The WSJ reports,"Al Qaeda-inspired militants seized control of Iraq's second-largest city on Tuesday in a brazen military operation that underscored the weakness of the Baghdad government across vast swaths of the country.
Hours after government forces fled Mosul in disarray following four days of fighting, Prime Minister Nouri al-Maliki declared a nationwide "state of maximum preparedness" but didn't indicate whether government forces were mobilizing to retake the Iraqi city, 220 miles north of the capital Baghdad.
The capture of Mosul by rebels linked to the Islamic State of Iraq and al-Sham, or ISIS, is the latest evidence of the weakness and disorganization that have beset Iraq's security forces since the U.S. forces withdrew from the country in December 2011.
It also underlines the group's determination to establish an Islamic emirate encompassing the Iraqi-Syrian frontier, weaken the already fragile Iraqi state and expand the theater of the three-year-old civil war in neighboring Syria".
"Residents of Mosul said they were shocked at the ease of the rebel takeover of government buildings, television stations and military installations where U.S.-supplied fighter airplanes, helicopters and other heavy weaponry are based".
"Jessica Lewis, a former U.S. Army intelligence officer, said ISIS fighters won a notable victory in Mosul.
"ISIS is designing its campaign around the state that it believes it has already created," said Ms. Lewis, currently research director for the Institute for the Study of War in Washington, D.C.
"I think that means that Iraq is going to start to look more like Syria. It's a gauge of the severity of the conflict and the trajectory that it's on. That's a very bad sign.""
"The U.S.-trained and equipped Iraqi security forces, which have floundered since the U.S. pullout, haven't succeeded in thwarting ISIS's emergence as a formidable paramilitary force. Its fighters regularly launch daytime attacks against government forces and have held the city of Fallujah, 36 miles east of the capital, since early January.
Mosul, the capital of Nineveh province, has been a longtime staging ground for al Qaeda-linked forces. Residents of the province have complained recently about stepped-up ISIS activities, including cash-for-protection demands to local businessmen and political officials—a major source of funding for the group's operations".
The threat of an attack rose sharply last Thursday, when fighters identified as ISIS commandos seized and occupied the nearby city of Samarra for 12 hours before withdrawing. Authorities in Mosul sounded the alarm, ordering government employees to go home and imposing a dusk-to-dawn curfew.
"Despite the security precautions, ISIS fighters raided the western half of Mosul early Friday, forcing military personnel and federal police forces to retreat over bridges to the eastern bank of the Tigris River, which divides the city.
For three days, residents in the eastern half of the city huddled in their houses and parceled out their ever-dwindling supply of food and other staples, as authorities tried to secure the city.
Mosul governor Atheel Nujaifi, appearing Monday evening on national television, made a desperate call for city residents to form ad hoc committees to defend themselves. But he fled on Monday night.
In the early-morning darkness of Tuesday, local resistance dissolved, as insurgents poured across the bridges separating east from west. According to witnesses, government soldiers fled on foot, leaving the streets littered with abandoned army vehicles, weapons and uniforms.
The vanquished soldiers knocked on doors and begged for civilian clothes, so they could escape without being identified, said Ahmed Khaza'al, a cosmetic dealer.
The victory by ISIS and its allies means they control sizable regions in at least three of Iraq's 18 provinces. Upon news of Mosul's fall, fears of more fighting rippled across the country.
Authorities in Kirkuk, a city near Mosul, have requested aid from Kurdish fighters known as Peshmerga.
The request for help from the Kurdistan Regional Government, a semiautonomous northern province, is likely to compound the troubles facing Mr. Maliki's government. It is already in a heated dispute with the KRG's government in Erbil, and stepped-up Peshmerga operations will only complicate it.
Mosul's capture also comes at an inopportune time for Mr. Maliki. His State of Law Coalition won a plurality of seats in late April parliamentary elections on promises that he would secure the country and subdue al Qaeda-linked fighters. But he still needs the support of other parliamentarians to secure a third, four-year term as premier".
