In the 17th Century Europe was under siege from the  Islamic armies of the Ottoman Empire. The caliphate spread north conquering  Christian Istanbul in 1453, taking Christian lands of  Greece and the Balkan states, with bloodshed, slaughter, terror  and destruction.  The Ottomans got right up to the gates of Vienna but were turned back by superior Western technology.

 Until stopped by Spain's Ferdinand and Isabella in 1492, Muslim Moorish armies were invading  and sieging  France getting all the way to Toulouse, Lyon  and close to Paris.   Today we are expected to welcome Islam with open arms and forget all that history. Nothing has changed  about Islam since then.
