“Sadly, many metropolitan leaders seem less than prepared to meet today’s current terrorist threat head-on, in part due to the trendy multiculturalism that now characterizes so many Western cities. Consider London’s multiculturalist Mayor Ken Livingstone, who last year actually welcomed a radical jihadist, Egyptian cleric Sheik Yusuf Qaradawi, to his city….

“In continental Europe, multiculturalism has been elevated to a kind of social dogma, exacerbating the separation between Muslim immigrants and the host society. For decades, immigrants have not been encouraged or expected to accept German, Dutch or British norms, nor have those societies made efforts to integrate the newcomers. Not surprisingly, jihadist agitation has flourished in Hamburg, Amsterdam, Madrid, Berlin and Paris as well as London.

“If cities are to survive in Europe or elsewhere, they will need to face this latest threat to urban survival with something more than liberal platitudes, displays of pluck and willful determination. They will have to face up to the need for sometimes harsh measures, such as tighter immigration laws, preventive detention and widespread surveillance of suspected terrorists, to protect the urban future.

“They will also need to institute measures that encourage immigrants to assimilate, such as fostering greater economic opportunity for newcomers or enforcing immersion in the national language and political institutions.”
