The neat thing about privilege is that it's basically invisible to the people with it. White privilege, check, male privilege, got that too. One thing I don't got is a level above that, that is United States citizen privilege, aka American exceptionalism. It gets really visible around US election times when from right across the political spectrum there are panicked cries of "If X wins I'm moving to Canada!" Yeah, nah, stay there and work on it. Especially don't leave all them nukes entirely in the hands of a doomsday cult. It's great being a US Ally and all, but we've seen just how transient and whimsical that can be over the last 20 years.
Internally, his point is valid, and he made his point in such a way it looks to an outsider that outsiders are fair game. In the wake of the mountain of lies that led to that obscene conflagration in Iraq, and with the long history of US meddling and overthrowing whole governments in the name of US corporate interests, that sort of a casual attitude from a presidential candidate is almost as scary as the current guy. By all means he can speak out against heavy weapons in civilian life. It's the trotting out his military service abroad (deeply weird military fetishization, but hey, 'Merica) calls out "Hey, leave us foreigners the fuck out of this." Especially while there's a whole lotta dronin' goin' on.
The above is all Good Information on Outside Perspective.
(Diplomatic skills still matter and are especially important in a President.)
