I think the problem with this line of thinking is that Putin can just "plan" to steamroll Ukraine in 2024, and that the only thing preventing Russia from already doing so is Putin's "plan." If Russia could steamroll Ukraine they would've done so already; geopolitics does not revolve around US election cycles. The war in Ukraine may end in 2024, maybe Ukraine's military will collapse thanks to all the pressure on it and their dwindling supplies, but it won't go according to anybody's "plan," as it's not up to Putin to decide when the war ends in a Russian victory outside of committing far more troops than they already have, which I don't see on the horizon given their current strategy seems to be working, albeit very slowly.
I agree that Trump's victory seems likely though, and if the situation in Ukraine wraps up in 2024 it's almost a sure thing.
But like, what's Russia going to do with that information that they wouldn't already do? There's no magic they can do here to make Ukraine fold faster.
