I can’t answer your question but can say why the heck should it matter. Why don’t we go after putin who we know has been bad for the globe for a very long time or what about netanyahoo and heck the kims. We may have done some shady things in the past but they at least followed international law (it might be debatable but not obviously ignoring it like this) or at least did it covertly because we still had some recognition it was wrong.















There are a few different ways fiction has dealt with that. Like one once you do it it updates time and you then remember it once you did it in the future, another you come back to there being two of you the non traveler who remembers and the traveler who does not. In some cases the world is changed but in others a new parralell world is made and sometimes the characters just don’t know. you could also have a thing where you return and everything is exactly the same but a parralell world was made that you just don’t go to when you return.
