While I ultimately believe you're correct (along with open borders and travel) I wish there were more rigorous proofs that this were the case.
I think about the line in West Wing: "Free trade is essential for human rights...the end of that sentence is 'we hope because nothing else has worked.' ...Chinese political prisoners are going to be sewing soccer balls with their teeth whether we sell them cheeseburgers or not, so let's sell them
cheeseburgers."
While war and human rights are different, they're also pretty correlated.
