Nah, the Abe assassination was still adventurism. It was still a single person acting alone and not as part of any organization. It’s a fortunate turn of events that the action ended up being appreciated enough that some reform happened as a result, but that was not a predictable outcome. In fact, the would-be Trump assassin had reason to believe he would have had a ton of popular support had he succeeded, given the Trump=Hitler and must be stopped at any cost rhetoric (if not action) by liberals. Both of them were definitely adventurisms.
