How concerned should President Zelensky be about the ongoing negotiations with Russia?

President Zelensky should be deeply concerned as the negotiations represent a life-or-death situation for Ukrainians. While Zelensky must ultimately approve any agreement, his negotiating position is weakened because the war isn't going well for Ukraine, limiting his leverage. The United States is coordinating with Ukraine through Special Envoy Kellogg, while separate negotiators engage with Russia. However, Ukraine's military challenges will significantly influence the final peace agreement terms, placing Zelensky in a precarious position where every detail emerging from these negotiations carries enormous stakes for his country's future.
