WP: The Islamic State’s trap for Europe [View all]

The Islamic States strategy is to polarize Western society to destroy the grayzone, as it says in its publications. The group hopes frequent, devastating attacks in its name will provoke overreactions by European governments against innocent Muslims, thereby alienating and radicalizing Muslim communities throughout the continent. The atrocities in Paris are only the most recent instances of this accelerating campaign. Since January, European citizens fighting with the Islamic State in Iraq and Syria have provided online and material support to lethal operations in Paris, Copenhagen and near Lyon, France, as well as attempted attacks in London, Barcelona and near Brussels. Islamic State fighters are likely responsible for destroying the Russian airliner over the Sinai. These attacks are not random, nor are they aimed primarily at affecting Western policy in the Middle East. They are, rather, part of a militarily capable organizations campaign to mobilize extremist actors already in Europe and to recruit new ones.
And listening to the likes of Trump and other GOP idiots, it's working.
