In an interview with Laura Haim on Canal Plus, a French television station, Mr. Obama noted that the United States also could be considered as “one of the largest Muslim countries in the world.” He sought to downplay the expectations of the speech, but he said he hoped the address would raise awareness about Muslims.

“And one of the points I want to make is, is that if you actually took the number of Muslim Americans, we’d be one of the largest Muslim countries in the world,” Mr. Obama said. “And so there’s got to be a better dialogue and a better understanding between the two peoples.”
