President Obama as per https://obamawhitehouse.archives.gov/the-press-office/2014/09/10/statement-president-isil-1

" ISIL poses a threat to the people of Iraq and Syria, and the broader Middle East -- including American citizens, personnel and facilities.  If left unchecked, these terrorists could pose a growing threat beyond that region, including to the United States.  While we have not yet detected specific plotting against our homeland, ISIL leaders have threatened America and our allies."
