A pacifist will not support use of the military for any reason, regardless of how justified it is.
Democrats pretend to be pacifists, and encourage mindless hatred of the military while failing to grasp any clue as to the constitutional purpose of the military. So, to try to demonstrate to the public that they are not spineless doves and raise their poll numbers, they overuse and misuse the military. This is why Kosovo happened, why the Middle East is in such turmoil right now.
Trump understands the proper use of the military. Thus, he will strengthen the military, but only use it when necessary. That is neither pacifism nor warmongering.
I get the sense that she half-pacifist. She supports use of the military for self-defense but not intervention. I agree with her on that. She probably would not agree with how I would use the military when it came time to fight (ruthlessly kill everyone and destroy all their stuff), but she gets the main issue. The military is not a social experiment.
