These days, Americans worry most about an economic recovery that President Obama calls "painfully slow". But on Saturday millions will remember the day al-Qaida terrorists flew airplanes into the World Trade Center in New York and the Pentagon in Washington. Another hijacked plane crashed in a field in Pennsylvania when passengers rebelled. Close to three thousand people died that day. Next year will be a big anniversary, ten years since the day Americans call 9-11.
But this September eleventh comes at an uneasy time. A large number of Americans say they oppose plans to build an Islamic center near the World Trade Center site in New York. This week attention centered on a Christian minister(基督教事工) with a small following in the state of Florida.
Reverend Terry Jones said he would mark the 9-11 anniversary by burning copies of the Quran(可兰经). He said he wanted to send a message to Islamic extremists. He said, "We are not hateful toward Muslims. We are not aiming this at Muslims, we are aiming this at Sharia law(伊斯兰教教法)."
Political and religious leaders around the world had condemned him. The plan even led the State Department to warn American travelers to avoid places where protests(抗议) might take place.
President Obama said burning Qurans could endanger American troops and invite more extremism. Defense Secretary Robert Gates called Mr. Jones on Thursday to urge him to reconsider.
Administration officials called the idea of burning Qurans "un-American." But they also agreed that it would be within constitutional rights, like protesters who burn American flags. The Constitution guarantees free speech and bars the government from restricting the practice of religion.
