If there was any question why the 20-year old Somali Refugee decided to ram his car into students then attack them with a knife, his Facebook manifesto should have covered it.

From Business Insider:

“America! Stop interfering with other countries, especially the Muslim Ummah,” the Facebook post said, according to a screenshot from NBC News, using the Arabic word for “community.” “If you want us Muslims to stop carrying out lone wolf attacks, then make peace with ‘dawla in al sham.’ Make a pact or a treaty with them where you promise to leave them alone.”

The post’s reference to “dawla in al sham” could be short for “al-Dawla al-Islamiya fil Iraq wa al-Sham,” a full name for Da’ish, the terrorist group also known as ISIS, the Islamic State, ISIL, or Daesh.

The terrorist group has been urging its followers to copy the Bastille Day attack in France, in which a man drove a large truck through a crowd of people, killing 84. ISIS also recently posted a video explaining how to conduct a knife attack, ABC News reported.

The assailant claimed that he felt threatened on campus while praying, that he didn’t like the way Muslims were treated in this country. Yet, all over the media today, we’re seeing “What was the Motive”?

Just a few minutes ago, IS claimed responsibility for the attack.

Reuters confirmed via twitter:

UPDATE: Islamic State claims responsibility for Ohio State University attack by Somali student – group's news agency

This is the 2nd attack by a Somalia in Columbus, Ohio this year. There is no indication the two crimes are connected but to ignore this seemingly growing threat seems dangerously naive. To pretend like we don’t know the “motive” is ridiculous.
