A 1st foreign policy test under Trump—escalating war danger & hurting civilians—was 2017 “Countering Our Adversaries Through Sanctions Act” targeting Iran, Korea, Russia. How candidates voted:

Harris: Yea
Warren: Yea
Booker: Yea
Bennet: Yea
Gabbard: Yea
Klobuchar:Yea
Sanders: No

To be clear this Act was in large part an attempt to push newly-elected Trump from the right on foreign policy; to test his willingness to pursue aggression and attacks against “enemies” and pressure him to abandon isolationist rhetoric in favor of Pentagon’s regime-change plots

That said, no Dem candidate has an internationalist/anti-imperialist foreign policy, and all have problematic records from that standpoint. It’s our job to push them and their support bases. To do that, it’s important to know where they all stand.
