This is an interesting history lesson with lots of good information.  I think it is important to remember that starting a war is an immoral act, regardless of the initiator's political party.  Ideally, we'd have a congress that would send the hawks back to the nest every time they floated the immoral idea to start a war.  Unfortunately, we don't have a dovish congress, even though Tulsi Gabbard has made some strong statements along these lines recently.
