More, yes, but I would not say much more. Of course, that depends on how you view Neoconservatives. The leading Neocons were radically pro Israel. Some carried Israeli passports. Of course, that aspect of the issue tends to be ignored because discussing it is like poking a hornet's nest. Would be interesting contribution to discuss the different interest groups which piled on with support, but there is no doubt about the leadership role of Neoconservatives in planning and directing the war. That role for U.S. intervention against Iraq went back to at least 1996.
