"Your reference to my remarks concerning Muslim terrorists, which appeared in the January 18, 2010, edition of Newsweek, is somewhat misleading.

"My comments concerning Muslim terrorist are well-known. I have often said that there are about 1 billion 200 million Muslims worldwide, and that the vast majority are peace-loving and decry terrorism. Nevertheless, I believe Osama bin Laden is the most popular figure in the worldwide Muslim community. If you estimate that 20 percent of Muslims support terrorism (defined as approving the intentional killing of civilians to achieve political goals) that would add up to more than 200 million Muslim terrorist supporters.

"I concur, as was stated by Abdel Rahman al-Rashad, the head of an Arab television channel who wrote in 2004: 'It is a certain fact that not all Muslims are terrorist, but it is equally certain, and exceptionally painful, that almost all terrorists are Muslims...We cannot clear our names unless we own up to the shameful fact that terrorism has become a Muslim enterprise, an almost exclusive monopoly, implemented by Muslim men and women.'

"In my judgment those facts allow profiling as a reasonable response, and I believe most of our readers have come to a similar conclusion. Why not poll them.

"I am sorry that it did not cross the mid of anyone at Newsweek that my reference was to terrorist supporters, and that a telephone call to verify was not made."

"Dear Mayor Koch. We would like to use your letter on Newsweek's letters page. Our policy is to include the writer's name, city, and state, so I wanted to confirm your city and state before we run anything. If you could please reply with that information at your earliest convenience we would greatly appreciate it. Thanks very much."

"Dear Mayor Koch. I'm sorry to inform you that it looks like we won't have a letters page in the magazine this week.

Occasionally we need the space for other content and I just learned this afternoon that we are losing the page this week for that reason. I apologize for any inconvenience."
