There are two risk factors for resuming military actions in Donbas. First of all, there has been no ceasefire for a long time. Secondly, the new Ukrainian President does not have full authority over the Ukrainian security services, including the military.
This message aims to question the power and legitimacy of Ukrainian authorities and is consistent with a recurring pro-Kremlin narrative about Ukrainian statehood.
President Zelenskyy is the Commander in Chief of the Ukrainian Army. There have been no statements made by President Zelenskyy or his representatives concerning alleged insubordination of certain military units deployed in Donbas.
The claim concerning President Zelenskyy’s lack of authority over the Ukrainian Army units is based on a statement of the head of the representative office of the unrecognised Donetsk People's Republic and has not been confirmed by other independent sources.
