The United States is calling for the complete and utter annihilation of ISIS in Mosul. Every last jihadist holdout must die.

At a press conference in Baghdad on Sunday, Brett McGurk, the Special Presidential Envoy for the Global Coalition To Counter ISIS, delivered a major update on the U.S.-backed coalition’s offensive against IS-held Mosul. Following a meeting with Iraqi and Kurdish leaders, McGurk confirmed that ISIS is on the brink of defeat, with the group’s fighters falling like flies on the battlefield.

Coalition forces are “committed to not just defeating them in Mosul, but making sure these guys cannot escape,” he emphasized.

Showing no mercy to an enemy that has forced the civilized world to revisit the question of man’s infinite capacity for barbarism, McGurk issued a final ultimatum to the apocalypse-minded jihadist insurgency:

We now believe that we are killing too many of their fighters and they are not able to replace them. That was not the case even a year ago. So the flow has gone down. We are going to continue to tighten it up. And any of the fighters who are left in Mosul, they are going to die there, because they're trapped.

While Iraqi and Kurdish forces have made major gains over the last few weeks, pushing ISIS militants into hiding, the U.S. government representative delivered his remarks with cautious optimism.

"Mosul's liberation is increasingly in sight, albeit with increasingly difficult fighting ahead,'' he told reporters. Iraqi forces have already retaken "some of the most difficult ground that we knew would have to be reclaimed…They're doing this in a dense urban environment facing a suicidal enemy that's using civilians as shields.''

Backed by unrelenting U.S. fighter pilots in the skies, Iraqi commandos have reclaimed eastern Mosul from the terrorist group, liberating hundreds of thousands of Iraqis subjugated to utter brutality under the iron-fisted rule of ISIS religious councils. Since 2014, the people of Mosul have lived under the oppressive doctrines of Salafist-inspired Sharia law, a body of laws that criminalizes everything from cigarette smoking to homosexuality.

But ISIS’ inhumane reign is soon coming to an end.

Last month, the Iraqi army deployed elite counterterrorism units into the perilous neighborhoods of west Mosul, liberating one district at a time from the blood-stained hands of ISIS fighters embedded in the densely-populated residential areas.

In a cynical ploy to shed as much blood as possible, ISIS leaders -- who fled the battlefield shortly before Iraqi forces surrounded Mosul -- are effectively using low-ranking fighters as cannon fodder. Chief among the cowards is ISIS “caliph” Abu Bakr al-Baghdadi, the bearded fanatic who gained infamy in 2014 after announcing his 7th-century modeled caliphate in a fiery sermon at the central mosque in Mosul. Abandoning his so-called holy warriors, Baghdadi retreated from Mosul before U.S. bombers were able to vaporize him off the face of the earth.

As of last week, “there were no more than 2,500 IS fighters left in Mosul and Tal Afar, a town about 60km (37 miles) to the west,” reports the BBC, citing U.S. defense officials.

The United States of America has a message for the 2,500 brutes who have chosen to remain in Mosul and wage a war against all that is good and decent in this world: You will all die.
