So for those unaware, zaluzhny is/was the commander in chief of the Ukrainian armed forces. Top dog of the military, officially under Ukrainian defense minister and president.

Well known previous tensions because zelensky (president) was all about symbolic useless stunts to keep westerb aid flowing, while zaluzhny wanted to preserve soldier lives and force a stalemate which was the best Ukraine could hope for.

Initially the west sold the idea of Ukraine winning everything back (zelensky-politicians and neonazis position) but that is unrealistic and now they are pivoting towards limited aid and Ukraine forcing a stalemate and negotiations (zaluzhny-military and moderate politicians)
