Emerson: Yes, they have. The Islamic groups' records, as well as official records released by the White House, show that the Executive Branch, the State Department, and the FBI continue to meet with radical or anti-American Islamic groups that openly support terrorist leaders (like Hasan at-Turabi of the Sudan) or even raised money for the defense of terrorists (such as for Musa Abu Marzook).
I suspect that there was the policy of not mounting terrorist attacks during the Clinton administration because of an implicit deal between that administration and the Islamic terrorists. With Clinton out and Bush in, that deal is off.
