Ukraine notified the Council of Europe of the partial suspension of some clauses of the European Convention on Human Rights and Freedoms in connection to recent changes in its martial law.
It is entirely possible that the Soviet leaders are about to develop a new form of "dictatorship by committee", giving them the advantage of appearing to be quasi-democratic.
When we speak of collective leadership, we mean a committee of a very few men, probably not more than five or six. The larger the membership, the greater the likelihood that fractionalization may occur, dividing the committee into antagonistic groups.
So the CIA calls him a dictator in one memo and not in another. I suppose that proves nothing in the end. Except that the CIA clearly doesn't understand Soviet governance based on the other details in the memo that you linked.
