I mean, many things are possible, including that outcome, whereas FTL and time travel do not seem to be possible. The question is, how probable is that outcome, and can you do anything to steer matters to it in a realistic way? I’d have to say that anyone sane enough to actually effect that outcome is too sane to come within a kilometer of even spending the time to plan it, let alone actually try it and die on the protective detail’s bullets.
