50 years from now the official position of representatives of powers (Russia, US, China, Israel, etc.) on their own actions from today will still be completely avoiding the topic. But some might, at best, halfheartedly admit that what happened "back then" was not their proudest moment and they could have done better, all while actually being worse. But that will be their water under someone else's bridge and as long as that water sill allows them to reap the benefits of their "not proudest moments" then it's just going to happen again and again with the next generations getting a minor point of conversation.
If Russia can "poison" Eastern Ukraine for their benefit, if the US can cut the legs from under a democracy for their benefit, if Israel can eradicate the people from a land for their benefit, etc. and live to fully enjoy that benefit, people are going to have these conversations on "ancient" history time and time again.
