MANCHESTER, United States: The Orlando massacre has exposed some of the sharpest contrasts yet between America’s presidential rivals, with Hillary Clinton on Monday (Tuesday in Manila) warning against demagoguery and rival Donald Trump declaring prospective immigrants from some nations persona non grata. Instead of unifying a politically divided nation, the worst terror attack in the United States since September 11, 2001 has widened the gap between the White House contenders over how to tackle extremism and keep Americans safe. Both candidates used their speeches in the wake of the shooting to enhance their commander-in-chief credibility, in starkly different tones. Presumptive Republican nominee Trump ratcheted up his pointed rhetoric, blasting Clinton for seeking to “allow radical Islamic terrorists to pour into our country” and suggesting the former secretary of state “has no clue” about radical Islam. “When I’m elected, I will suspend immigration from areas of the world where there is a proven history of terrorism against the United States, Europe or our allies, until we fully understand how to end these threats,” Trump said during a highly-anticipated national security speech in New Hampshire. “We cannot continue to allow thousands upon thousands of people to pour into our country, many of whom have the same thought process as this savage killer,” he said, referring to the Orlando gunman, whom US authorized suspect was radicalized by Islamist propaganda. Clinton made no mention of Trump in her speech, instead urging Americans to reject political partisanship and “stand together” to defeat terrorism. “The Orlando terrorist may be dead, but the virus that poisoned his mind remains very much alive and we must attack it with clear eyes, steady hands, unwavering determination and pride in our country and our values,” she said.
