I’m new at this so forgive if I do this wrong but you might have him review the original authorization approved by congress. Many forget that in that document, the WMD’s were listed as merely the forth reason for the ouster of Saddam.
Genocide of his own people was listed before WMD’s and imo should be reason enough, unless this person feels Genocide is ok.
He and the people defending him are more of those “The war’s for oil” retards...and we all know how stubborn those nitwits are. He could care less what Congress said (I’ve already informed his peanut brain that it is Congress, not the Useless Nitwits, that the President needs authorization from).
