Mr. Obama in his weekly address on Saturday said that this year's anniversary will be one of "service and remembrance."

"We need to make sure we're speaking to a very broad set of audiences who will be affected by the anniversary," Benjamin J. Rhodes, a deputy national security adviser, said in a telephone interview on Friday.

That may be, but some American counterterrorism and intelligence officials are complaining that the White House missed out on tying together the 10th anniversary with recently announced strategies to combat terrorism and violent extremism into a more coherent, longer-term plan. "They don't do that kind of long-term planning," said a senior counterterrorism official, who spoke on condition of anonymity to avoid disciplinary measures from the White House. Mr. Rhodes rejected that criticism, saying these themes have threaded through many of Mr. Obama's speeches in recent months.
