Obama in traditional Muslim dress at Maryland Wedding
O'Reilly claims the President has consistently failed to identify the terrorist threat facing America, has allowed ISIS to run amok in the Middle East, and will not admit to his mistake.
He said: 'There is no question the Obama administration's greatest failure is allowing the Islamic terror group ISIS to run wild, murdering thousands of innocent people all over the world, including many Muslims.
'That group is killing innocent people in order to impose a radical version of Islam on the world. The jihad is solely based on theology, perverted as it may be.'
Obama's refusal to use the phrase 'Islamic terrorism', preferring instead to say 'militants' or simply 'terrorists' has long been a sore spot for his Republican detractors, including Donald Trump.
