Hillary Clinton in her own words (from March 6, 2003):
" With respect to whose responsibility it is to disarm Saddam Hussein, I do not believe that given the attitudes of many people in the world community today that there would be a willingness to take on very difficult problems were it not for United States leadership. And I am talking specifically about what had to be done in Bosnia and Kosovo, where my husband could not get a Security Council resolution to save the Kosovar Albanians from ethnic cleansing. And we did it alone as the United States, and we had to do it alone. It would have been far preferable if the Russians and others had agreed to do it through the United Nations -- they would not. I'm happy that, in the face of such horrible suffering, we did act."
So all of this was acceptable to her since it was her husband who was president.
Pelosi:
"As a member of the House Intelligence Committee, I am keenly aware that the proliferation of chemical and biological weapons is an issue of grave importance to all nations. Saddam Hussein has been engaged in the development of weapons of mass destruction technology which is a threat to countries in the region and he has made a mockery of the weapons inspection process."
