It is very easy to end the conflict, it is just that the only realistic scenario for ending the conflict does not suit either Kyiv or Washington.
I think you're wrong, Putin's death suits Kyiv just fine. Not sure about Washington, he's been dead for a while so probably has no strong opinions about this.
That's just not true there were many articles analyzing successors in case of Putin's sudden demise
The context was "realistic scenario". Your wet dreams about an even more deranged KGBist taking over after Putin don't count.
This is Putin's war. It's useless to most Russians, oligarchs and ordinary alcoholics alike. No, Putin's death
doesn't guarantee the war would end, but Putin staying in power
guarantees the war will not end (even if Ukraine makes some concessions for some hypothetical peace deal). All other things being equal, Putin's death (whether of natural causes or perhaps suicide in a bunker if the war continues to defy his dreams) is a more realistic chance, small as it may be, at long-term peace, compared to the Z-tarded fantasies of Ukraine just giving up and disappearing off the map.
