There is no better example of these "no go" zones than one neighborhood in the city of this latest horrific attack — the municipality of Molenbeek in the city of Brussels. In attack after attack, from 9/11 to Madrid to Paris to Brussels, the trail seems to come back repeatedly to Molenbeek. At least three of the terrorists of the November 2015 Paris attack grew up and lived there. In fact, one of the key terrorists of the Paris attack, Salah Abdeslam, fled back to Molenbeek where he knew he could find sanctuary. It is telling that Abdeslam effectively hid in plain sight there for weeks in the same city as the headquarters of NATO and the European Union.
