In an op-ed for The Telegraph, Valerii Zaluzhnyi, Ukraine's ambassador to Britain and former commander-in-chief, hits Zelensky when he's weakened, talking about Ukraine's unpreparedness in Feb 2022, corruption, and "peace, even in anticipation of the next war."
Zaluzhnyi also suggests that the "deployment of nuclear weapons on Ukrainian territory" could be a security guarantee for Ukraine to end the war, which Putin wouldn't agree to, even if he were drawing his last breath in his bunker.
