From recent comments today, it sounds like Zelenskyy is setting the stage for Ukraine officially abandoning it's goal of joining NATO. It is something which has been all but impossible since 2014 anyway, and is even more unlikely to ever happen now, but this could be part of a deal to get Russian troops to withdraw back to pre-2022 invasion positions.
It seems clear now that Russia will be unable to achieve it's goal of taking over Ukraine and installing a puppet government so Putin may settle for some lesser "victory condition".
If that's the off ramp that Putin needs (even if it's not about that), than so be it. Not sure how there can be long term stability for Ukraine with Putin just waiting his turn for another shot.
