A new Islamic State video released titled “Message of the Mujahid” calls on Western jihadists unable to travel to territory controlled by the terrorist group to conduct attacks at home. The message also offers a pointed rebuke of British Prime Minister David Cameron and the U.S.-led bombing campaign.

“A message to all of the brothers who cannot do Hijrah, I advise you to respond to the call of the sheik, the mujahid (Holy Warrior) Mohammed al-Adnani, to cause terror in the hearts of the kuffar (unbelievers),” the unidentified Islamic State spokesman said. “You are living in the West, you can cause terror in the hearts of the kuffar, right in the center of the kuffar in the center of all that shirk (polytheism), you can cause terror right from within.

“So unlike us, you can cause real damage right within the heart of Dar al-Kuffar (Land of Unbelief), so rise up my brothers. Rise up!”

He starts out the video mocking Cameron and the Western leaders for thinking they can defeat the Islamic State with bombs dropped from the air, chiding them that if they were “real men” they would send ground troops to fight them.

“You know that in the hearts of your men, they’re cowards,” the spokesman says. “So America, you think you are a superpower, when in fact if you were a superpower, you wouldn’t need these 40 nations to come and fight us.”

“Know that all power belongs to Allah, and Allah is with [the pious Muslims], so you could send your planes above us, but know that Allah is above your planes,” he continued. “You are fighting people who love death more than you love life.”

The message warns that the West and their Muslim allies can send all of their men, reserves, and backups, and the Islamic State will send them back one-by-one in coffins.

In a special message to British Muslims, he says that the caliphate has been re-established and calls on them to leave the land of the unbelievers and come to the Islamic State.

“If now is not the time to do Hijrah then when is the time,” the spokesman asks. “Why are you still in Dar al-Kuffar? What does Dar al-Kuffar have to offer you? We have the Islamic State here, and we are fighting jihad.”

He tells them that the “despicable” West has nothing to offer them.

This reaffirms the Islamic State’s desperate desire to inspire attacks against Western targets and hopes to turn Muslims against their home countries.
