While I can like your post for going deeper than [I just read headlines to fuel my rage], my leanings still tilt toward the soon to be DNI nominee. That particular interview was a couple of years ago, but most of what formed the basis for her positions on things like geopolitical affairs was already cemented, namely her education in congress. For a deeper dive and expanded presentation of her positions, I'd recommend giving her book a try; you can get it on audiobook from DoD MWR library.
I would even go so far to say that she is not an isolationist, but rather holds to a FAFO military readiness posture (speak softly but carry a big stick), that runs contrary to contemporary DC's never met a conflict they didn't like mentality.
And I wholeheartedly subscribe to her supposition that had this election gone the other way, we would have found ourselves in a nasty brawl, purely out of a need to assert the image of strength by a weak individual. I believe we dodged a big fucking bullet.
