I don’t think there will be any discussion of specific plans to end the war. This meeting is likely going to be about generalities and ideas on the post-war landscape. When the time comes, after the inauguration, Trump is going to crack the nuts of Putin and Zelensky. The way to end this war is to make both of them thinking they’re going to lose a lot more if they don’t stop it.
The likely peace deal will probably look a lot like the one Biden and Boris torpedoed a couple years ago except that status quo in Crimea will stay the same - de facto but not official Russian territory
The big win for Trump in negotiations may be Russia walking away from its support of Iran's nuclear program to become a competitor with Iran in oil and gas.
Zelensky will be forced to hold elections and Trump may refuse to deal with him until after the election . Especially if Zelensky is obstructive to Trumps objectives.
Zelensky will be hated by the Ukrainians for destroying the country to get worse peace terms than he was offered weeks into the conflict and he will not be re elected . He may have to leave the country for his own safety
Trump will try pressure the Europeans to foot the bill for the rebuilding of the Ukraine while still giving American companies a piece of the action
What Zelensky may get is parole and a promise not to prosecute for corruption and the theft of massive amounts of aid money
