Zelensky wants to restructure the state and military leadership in the Ukraine war - "replacement" of several top leaders is planned. In the past there have been repeated differences between the president and Commander-in-Chief Saluzhny.
The military called for a mobilization of up to 500,000 people. The president initially rejected the request and demanded more details. Only recently did he criticize the lack of fighting power due to domestic political resistance, not least probably from the president himself.
