“Some witnesses said he shouted ‘Allahu akbar’ (‘God is great’ in Arabic) but the motive for the attack is unclear.”

A group of Japanese men flying airplanes bombed Pearl Harbor today. Some witnesses say that their planes bore the markings of the Japanese empire, but the motive for the attack is unclear.

Also, “Allahu akbar” is not “God is great” in Arabic. It means “Allah is greater,” i.e., greater than your god.

“Germany knife attacker kills man at Grafing station,” BBC, May 10, 2016:

One man has been killed and three others wounded by a knife-wielding man near Munich, with police investigating a possible Islamist connection. The man attacked four commuters shortly before 05:00 (03:00 GMT) on Tuesday at Grafing station. One of the victims died of his wounds in hospital. A 27-year-old German man was eventually overpowered by police and arrested. Some witnesses said he shouted “Allahu akbar” (“God is great” in Arabic) but the motive for the attack is unclear. The suspect has been identified as a 27-year-old German national, apparently from the Hessen area of central Germany. An Upper Bavaria police spokesperson said that a “political motive” had certainly not been ruled out. Police spokesman Karl-Heinz Segerer told German television that the man “expressed political motivations” during the attack. He gave no details, saying it was a matter for the investigation. Bavarian Interior Minister Joachim Herrmann said it was a terrible attack and that a second victim had suffered life-threatening injuries. He said that as well as a possible Islamist motive, police were trying to determine if the man had drug-related or psychiatric problems….

Of course. Psychiatric problems. That’s it. A global outbreak of madness, affecting millions.
