ABC This Week interviews during 2020: on Foreign Policy

Doug Jones: Impeachment warranted if withheld Ukraine aid helped Russia

Kirsten Gillibrand: Israel went in wrong direction barring Congressional visit

GILLIBRAND: Congress has a duty to make decisions about whether we give aid, how we protect allies such as Israel with qualitative military edge. I don't know why Netanyahu would want to deny members of Congress to come to Israel if they expect us to be that never-ending partner and friend.

Q: They talk about the BDS movement ("Boycott, Divestment, Sanctions" directed against Israel)..

GILLIBRAND: In this country, we don't deny people the right to participate in conversations about their views and their values. Unfortunately, Netanyahu has allowed a law that says if you support the BDS movement they can prevent you. Any time you are undermining basic free speech rights and human rights you're going in the wrong direction.

Pete Buttigieg: Pay attention to assessments of intelligence agencies

A: I think it would make more sense to have that happen in a framework of concrete achievements. You don't just get to have a meeting, declare the nuclear threat to be over, then wind up being embarrassed and contradicted by your own intelligence chiefs. As a military officer serving overseas, I was part of the intelligence community. And there is not a more reality-based group of people in this country. You actually have to understand and legitimize and take seriously their assessments before you have any business having a one-on-one with the leader of a hostile foreign power like North Korea.

Julian Castro: Strengthen our relationship with allies to keep us safe
