The only thing Trump can do in Alaska meeting is to agree to give back Alaska.
Hard to find something crazier than have ceasefire talks without one Waring party partaking.
Most likely the meeting wont even happen.
There is still a big self-imposed by Ruzzia barrier to have conversations directly with Ukraine after all the propaganda that has corner=painted Putin into a maximalist goal. However in diplomatic terms there needs to be some work being done and the US is what we have to make the mediatior role.
Regardless, there is little chance of Putin accepting anything that is not a strategic victory, while the situation of the front and the economies is not there yet. Putin's current proposal to Ukraine is to conceed the most fortified part of the front, for free, on the simple promise of "starting talks" - so the proposal is "give me what I want and then we keep talking".
In diplomatic terms this means "I do not want peace, I am just saying something that I know you will not ever take".
It will take two or three years to bring Ruzzia to something near a real interest in talking. More loses, more economic damage.... All ok with the US.
