What happened in Brussels was a co-production by adepts of two sick ideologies. The first one is Islamism in its many versions, including Khomeinism in Iran, Talibanism in Afghanistan, Salafism in Arab countries, Boko Haram in Nigeria, and ISIS and its offshoots across the globe. It will remain firmly in place until it implodes under the weight of its savage contradictions, as did the old Soviet Union, or is defeated in a war, as was the case with Nazi Germany and imperialist Japan. The other co-producer, the mushy and politically correct "liberal” ideology that has seduced segments of opinion in Western democracies, can and must be combated by all those who wish to protect the democratic system in an increasingly dangerous world.
