When it comes to the opinion-makers and experts we listen to on matters of foreign policy, it's neither new nor enough to ask: where are the women? We also have to ask where they aren't.We need not go very far for an answer: The Washington Post recently compiled data from events hosted by six leading think tanks in Washington, DC. They found that not a single woman spoke at more than 150 events on the Middle East. Of the 232 total events included in the Post's data set, fewer than 25 percent of the speakers were women.
