What concerns exist regarding the negotiations between Trump and Putin in relation to Ukraine?

The primary concern is that President Zelensky might be excluded from critical negotiations between Putin and Trump regarding Ukraine's future. As mentioned by Dov Zakheim, 'Whether Zelensky will even have a say is an open question,' highlighting the possibility that decisions affecting Ukraine's sovereignty might be made without Ukrainian representation. This situation raises significant alarms about potential agreements that could undermine Ukraine's position and interests in resolving the conflict. The dynamics suggest a concerning pattern where powerful nations might negotiate over the fate of smaller states without their participation, reminiscent of historical precedents where great powers determined the destiny of smaller nations.
