The European Union's official statistics on terrorism are dramatic:
"In 2016, a total of 142 failed, foiled and completed attacks were reported by eight EU Member States. More than half (76) of them were reported by the United Kingdom. France reported 23 attacks, Italy 17, Spain 10, Greece 6, Germany 5, Belgium 4 and the Netherlands 1 attack. 142 victims died in terrorist attacks, and 379 were injured in the EU. 1,002 persons were arrested for terrorist offences in 2016".
These countries all tried to integrate Muslim communities, but all came to the same dead end. "As long as that continues, the failure of integration will pose a mortal threat to Europe", the Wall Street Journal wrote after a suicide bombing that killed 22 people in Manchester. According to a new book by the French reporter Alexandre Mendel, Partition: Chronique de la sécession islamiste en France ("Partition: A Chronicle of the Islamist Secession in France"), multiculturalism is leading to the separation of European societies.
