What significant diplomatic situation is President Zelensky facing during his visit to Turkey?

President Zelensky of Ukraine is currently in Ankara meeting with Turkish President Erdogan while finding himself excluded from crucial discussions that will determine Ukraine's future. This diplomatic isolation comes at a critical time when decisions about Ukraine's fate are being made without its leader's direct input. The situation highlights the challenging position Ukraine occupies in current geopolitical negotiations, as external powers appear to be making determinations about the nation's trajectory without adequate Ukrainian representation at key talks.
