Guess it's something I don't really think about due to the whole "something I have exactly zero control over" aspect, but it is something I can definitely see happening in some shape or form. Whether it be Putin deciding to say "fuck it" because he craters Russia in his personal forever war with Ukraine and figures he can erase a lot of mistakes by firing off his nuke collection, us flipping out over America losing its status as THE world power because other countries with their more authoritarian leaderships actually have leaders focused on other stuff than manufacturing viral soundbites against the other party OR those other countries deciding that if we're not stepping out of the way, they'll move us out of the way by whatever means necessary.
Whatever happens, I hope they have the consideration to wait a while. I have this list of TV shows and movies I want to watch and would prefer if none of this WW3 stuff gets in the way of that.
