I doubt either of them think war is on the horizon and if they do they probably believe they can avoid it (Kamala by continuing the ukraine war and trump by ending it)

I have to disagree here. Both sides have been at least drumming up support to attack Iran, unsure how this will look at the moment, but they agree that Iran is their "biggest" target and are not shy in saying so. That rhetoric tied with the unwavering support for isntreal gives either side the consent to target Iran.
