Who was Abdelhamid Abaaoud? Son of a Moroccan immigrant, he had a comfortable upbringing. Thrown out of schools, he became a thief. After getting out of prison, he hung out at a dive bar full of drug dealers. In 2014, Abdelhamid suddenly moved to Syria. He was first seen in a video where he dragged corpses with a pick-up truck, reports the New York Times. But, he was soon involved in many terrorists operations. He reportedly knew Mehdi Nemmouche, who admitted to killing four people during a May 2014 attack on a Jewish museum in Brussels, Belgium, reports CNN. He also supposedly contacted Sid Agmed Ghlam, who planned an attack on a church in Villejuif, France. He was even linked to Ayoub El Khazzani, the terrorist who attempted an attack on a French train in August.
I guess you can get the law-abiding Muslim out of Africa, but you can't get the Islamic blood lust out of the culture - even if born in Belgium.
A lesson here.
