MSNBC / MGN WASHINGTON (AP) – Fears of terrorism are hanging over America’s holiday season, so President Barack Obama is planning a series of events this week aimed at trying to allay concerns about his strategy for stopping the Islamic State group abroad and its sympathizers at home. Obama’s visits to the Pentagon and the National Counterterrorism Center are part of a push to further explain his terrorism-fighting strategy, White House officials said, after a prime-time Oval Office address last Sunday that critics said failed to do much to reassure the public. Another goal is to draw a contrast with Republican presidential candidate Donald Trump and his inflammatory remarks about Muslims. The Obama administration has warned Trump’s rhetoric emboldens extremists looking to pull the U.S. into a war with Islam. “Terrorists like ISIL are trying to divide us along lines of religion and background,” Obama said Saturday in his weekly radio and Internet address, using an acronym for the extremist group. “That’s how they stoke fear. That’s how they recruit.” In the coming week, he said, “we’ll move forward on all fronts.” The public relations campaign, one week before Christmas, comes as the public is jittery about the specter of terrorism after the mass shooting in San Bernardino, California this month and the Paris attacks a few weeks before. Seven in 10 Americans rated the risk of a terrorist attack in the U.S. as at least somewhat high, according to an Associated Press-GfK poll. That was a sharp increase from the 5 in 10 who said that in January.
