McCain and Graham actually both started out as comparatively dovish realists before becoming extreme neocons; McCain opposed the interventions in Lebanon, Somalia and Haiti while Graham opposed the Bosnia and Kosovo bombing campaigns. So their IRL younger versions would have probably been fairly reasonable if they'd been President during the Cold War.
I picked Carly, since there's no evidence of her ever having sane foreign policy views, and she beat Graham to the "shoot down Russian planes" idea by a month, although McCain beat her to it by a day it looks like.
Cruz and Trump OTOH are firmly in the realist camp and are arguably more dovish overall than the Clintons.
I'd say it's beyond argument.
