Obama remembers Sept. 11, calls for unity

Amid an atmosphere of unease, President Barack Obama wants Americans to mark the ninth anniversary of the Sept. 11 attacks by recapturing the sense of common purpose felt on that dreadful day. "If there is a lesson to be drawn on this anniversary, it is this: We are one nation — one people — bound not only by grief, but by a set of common ideals," the president said Saturday in his weekly radio and Internet address.

"By giving back to our communities, by serving people in need, we reaffirm our ideals — in defiance of those who would do us grave harm." Obama himself was marking the day nearly 3,000 people died in terrorist jetliner attacks with a moment of silence at 8:46 a.m., the time the first plane hit the World Trade Center in New York City. The president also planned to attend a memorial service at the Pentagon and participate in a service project in the Washington area. First lady Michelle Obama was to join former first lady Laura Bush in Shanksville, Pa., where the fourth plane crashed after passengers rushed the cockpit. Vice President Joe Biden is in New York for the service at ground zero. But this years remembrances take place in an unusually tense environment, amid growing public suspicion of Muslims and controversies over an Islamic community center and mosque planned near ground zero and a Florida pastors threat to burn Qurans on Saturday.

By late Friday, it appeared the Rev. Terry Jones had backed off his plan to burn the Muslim holy book, following international condemnation. In New York, protests were planned for Saturday by supporters and opponents of the proposed mosque. Obama alluded in his radio address to the contentious atmosphere, though without specifically addressing either controversy. "This is a time of difficulty for our country," Obama said. "And it is often in such moments that some try to stoke bitterness — to divide us based on our differences, to blind us to what we have in common. "But on this day, we are reminded that at our best, we do not give in to this temptation," Obama said. "We stand with one another. We fight alongside one another. We do not allow ourselves to be defined by fear, but by the hopes we have for our families, for our nation, and for a brighter future." At a White House news conference Friday Obama denounced the threatened Quran burning, said Muslims have the same right as any other religion to build near ground zero and issued a full-throated appeal for religious tolerance, reminding Americans: "We are not at war against Islam."
