Inevitable, not at all. There are places in the world that have their problems, there have been wars already where nukes could've been used.. and not one has dropped in war since WW2. The horror of the aftermath is such that even a warhawk is not willing to bring about that fate.
I doubt even Trump, who has thus far only managed to constantly fall below every low expectation I had.. would think that nuclear war is a smart thing to engage in. Just think of what would happen to his golf courses >.>
