John Kerry's stern denunciation of Syria's use of chemical weapons on Monday put the Secretary of State in an exclusive club: members of the United States government who met with world leaders they later wanted to attack.

The conditions of that meeting were distinctly different than Kerry's with Assad. For example, Rumsfeld and the Reagan administration knew that Hussein had and was using chemical weapons in that conflict.
