As the civilized world joins the United Kingdom in mourning the deaths of 22 innocent people, children included, in a horrific suicide bombing attack at an Ariana Grande concert in the Manchester Arena, police and counter-terrorism agents are scouring to find any accomplices linked to the perpetrator, a 22-year-old Muslim male named Salman Abedi.

Terrorist attacks on major European cities are beginning to feel routine. But they shouldn’t be. This isn’t normal. The Islamic terrorist reportedly blew himself up with a device meant to send nails flying into human flesh. At the local children’s hospital in Manchester, doctors are removing shrapnel from the faces of young girls. This isn’t normal. It never was. It never is. And it will never be normal.

But that’s not what Sadiq Khan, the Muslim mayor of London, thinks.

In September 2016, Khan actually had the gall to say that citizens in big cities should just get used to terrorism.

At a glitzy event in New York City called “Building Progressive, Inclusive Cities” alongside his counterpart in the Big Apple, far-left Mayor Bill de Blasio, Khan talked about the virtues of immigration and multiculturalism, explaining that some sacrifices had to be made.

Terror attacks are “part and parcel of life in a big city,” Khan later told the Evening Standard just hours after police foiled multiple terror attacks in New Jersey and New York.

Once hailed as a “progressive” Muslim that would inevitably challenge regressive Islamists, Khan echoed the same excuse shared by European leaders across the West. After a series of terror attacks in France, the French Prime Minister told his countrymen that France “will have to live with terrorism.” In other words, terrorism is the new normal.

Serving as London’s mayor for less than a year, Khan has a history of controversial remarks.

During the London mayoral election, Khan apologized after a video surfaced showing the Labour party official calling moderate Muslims “Uncle Toms.”

And in February, Khan overstepped his authority as mayor and demanded that President Trump be denied a state visit to the United Kingdom, citing the American administration’s “cruel” immigration policies.

Khan is so devoted to the tolerant tenets of multi-culturalism that he even served as “legal consultant’ to 9/11 bomber Zacarias Moussaoui, and "shared a platform" with terrorist Yasser al-Siri, who once said American soldiers’ corpses should be “dragged in the streets,” according to Daily Wire’s Hank Berrien.

But Khan isn’t the only one who shares a nearly cultish belief in multiculturalism.

Unfortunately, Europe is littered with bureaucrats and politicians who think exactly like Khan. If all stays the same and the European Left has its way, then Europe (and perhaps even the West) as we know it is dead.
