Last week, a 12 year-old Iraqi-German boy was apprehended after he tried two bomb two Christmas markets in a town in Germany. 

There have been dozens of foiled Islamist terrorist attacks in Germany, France and elsewhere in Europe in recent weeks. The authorities are surely building-up their intelligence systems. Again, today in Belgium, raids on an apartment yielded guns and ISIS flags.

Unfortunately there will always be terrorist attacks when you have so many crazy Islamists motivated by ISIS.
