I expect that Russia will avoid peace talks until they see how the American elections turn out (and if the current American government can get over the current roadblocks to arming Ukraine). If Trump wins then either Europe has to compensate for the loss of American support, driving a wedge between Europe and the US, or Europe fails to make up the shortfall and Ukraine has a far weaker hand in negotiations.

I can imagine it's also possible that Ukraine is doing this right now specifically because Russia probably wants to wait for the American elections.

Whatever happens, I wish Ukraine the best of luck. I hope we give them the strength to get either a good deal or a victorious end to the way, whichever they choose to go after
