Will ISIS Attack on the June 29 Anniversary of the Caliphate?

“There is a concerted effort to appear as relevant as ever, stronger than ever and more defiant than ever in the face of international opposition,” he added, predicting the group would be planning "more violence, more advances, more attacks."

They may not be specifically aiming for a U.S. attack; the Islamic State hacking division just days ago published the names and addresses of Italian military commanders online as targets, the faces of the women cut out.

Maurizio Gasparri, a senator with Silvio Berlusconi’s Forza Italia party, last month accused the government of "bringing in Islamist fundamentalists and using Italian ships as taxis for potential jihadists" with migrants trying to get from Libya to Italy.

Italian foreign minister Paolo Gentiloni warned that they "don’t have months and months" to address the migrant crisis with humanitarian and national security implications. "The double risk of an advance of the Islamic State group in Libya and the waves of migrants means we are in a race against the clock," he told Corriere della Sera.

ISIS' desire to sack Rome warranted an entire e-book, predicting “recruits” from among "left-wing activists" in Europe sympathetic to their cause “will give intelligence, share weapons and do undercover work for the Muslims to pave the way for the conquest of Rome." They also predicted, though, that the Mafia will put up a fight.

Here in the United States, nearly a month ago the Pentagon raised the security level at military bases to the highest level since the 10th anniversary of 9/11.

FBI Director James Comey warned around the same time that "the haystack is the entire country" when it comes to finding ISIS.

"We are looking for the needles, but increasingly the needles are unavailable to us. ... This is the 'going dark' problem in living color," Comey said. "There are Elton Simpsons out there that I have not found and I cannot see.''

As far as specific threats for America, a message to “brothers and sisters fighting for the Sake of Allah” was posted on an online file-sharing site days after the Garland attack by a user claiming to be an ISIS-affiliated American.

"We have been watching closely who was present at this event and the shooter of our brothers. We knew that the target was protected. Our intention was to show how easy we give our lives for the Sake of Allah," said the message, which was tweeted by a user who described him or herself as “stuck in the lands of the kufr [nonbelievers],” with a photo of an ISIS flag and a residential suburban neighborhood in the background.

The message said ISIS has stationed “71 trained soldiers in 15 different states ready at our word to attack any target we desire.”

“Out of the 71 trained soldiers 23 have signed up for missions like Sunday, We are increasing in number bithnillah. Of the 15 states, 5 we will name… Virginia, Maryland, Illinois, California, and Michigan,” the posting continued. “The disbelievers who shot our brothers think that you killed someone untrained, nay, they gave you their bodies in plain view because we were watching."

"The next six months will be interesting."
