Donald Trump delivered a strong speech Monday on thwarting terrorists and crushing ISIS while cleverly disguising it as an address on national security policy.For once in recent days, Trump didn't get too clever. He lashed out at President Obama and Hillary Clinton for allowing Iraq to become fertile soil for the creation of ISIS. He didn't claim they had founded ISISâthat was Trump's position last weekâonly that their policies had allowed the terrorist group to flourish.So the speech marked a sorely needed improvement in Trump's credibility. By failing to reach a status of forces agreement with the Iraqi government and then pulling the last contingent of American troops out of the country, Trump said Obama and Clinton in effect launched ISIS on the world stage.//
