This world is so insane, Truck of Peace hits even Muslims now. No excuses though, Muslim, Christian or whatever, you drive that truck, you should die too.
People are hitting back. Muslims think they're going to keep attacking people with no response. That could have worked when they were living in their third world countries and coming to Europe just to blow themselves up, but now their families are here and can be targeted. Unfortunately terrorism is not the best way of fighting these fanatics, we should be better than this and fight them openly by deporting them and banning their extremism.
Automatic deportation for immigrants found having links with terror groups. For naturalized dual-citizens, revoke citizenship and deport them to their other country. For mono-citizens, look them up with bail or parole.
