Comment: The title says "In aftermath of Berlin Christmas market attack, Germany’s resilience tested". 

That wasn't the first attack on innocent civilians by a follower of Islam in Germany. Millions of Muslims have swarmed into Germany and Muslims have attacked Germans before.

And,  in other European countries like Netherlands, Belgium, France. etc.,  there have been more attacks than ever by Muslims. It seems the more Muslims the greater the possibility of threats or attacks on innocent,  civilian non believers.

People in Europe are nervous. Security is high and police are everywhere. What a way to live.

By the way, what is it that inspires, incites and leads some Muslims to threaten or to try to attack or to attack, maim and kill innocent, civilian non believers.?

Where do some Muslims get the idea they must attack, maim and kill innocent, civilian non believers.?
