WASHINGTON — President-elect Barack Obama’s aides say he is considering making a major foreign policy speech from an Islamic capital during his first 100 days in office.

So where should he do it? The list of Islamic world capitals is long, and includes the obvious —Riyadh, Kuwait City, Islamabad — and the not-so-obvious — Male (the Maldives), Ouagadougou (Burkina Faso), Tashkent (Uzbekistan). Some wise-guys have even suggested Dearborn, Mich., as a possibility.

Clearly it would be cheating for Mr. Obama to fly to Detroit, talk to Dearborn’s 30,000 Arab residents and call it a day. And Male and Ouagadougou, while certainly majority Muslim, can’t really be what Mr. Obama’s aides have in mind when they talk about locales for a high-profile speech that would seek to mend rifts between the United States and the broader Muslim world.

The consensus, after an entire day of reporting, is Cairo.

Why Cairo? It’s a matter of elimination. I called Ziad Asali, the president of the American Task Force on Palestine, to gauge his thoughts. “Damascus would be cool, except it would look as if he was rewarding the Syrians and it’s too soon for that,â€
