I had never before had any need to find the Ukrainian constitution. Here it is:-
The responsibilities of the President come towards the end and it would take a lawyer to determine which clause trumps another. They must both enact the decisions of the parliament and revoke them. I assume though always by request. What’s clear though is that the President is the Head of State, responsible for foreign affairs, but that the Parliament not only make the laws but can remove the President via impeachment, requiring a super majority to do so.
Which they did. Meaning an overwhelming majority wanted rid of him.
Is it any wonder sanctions were threatened? If a President refuses to enact the will of the people as expressed through their representatives then their friends help.
Of course the eastern units used their own arms to start with but no army fights without resupply and Moscow resupplied. How else could they continue?
The Minsk agreements? There were two, neither respected by Putin. Russia were involved from day 1 in the eastern states, provoking, supplying and then getting directly involved. No doubt you will claim this is all just western spin and only Putin tells the truth:-
