The Russians held a referendum there. Does Russia have such a right?
What about international law?
Why doesn't Russia hold a referendum in its national republics?
The Russians killed tens of thousands of Chechen separatists in Chechnya to "restore constitutional order."
What were Russian troops doing in Kyiv in 2022? wanted to hold a referendum? Or is this just a classic occupation of a neighboring country?
Give us your arguments.
I asked a question, so I don't have an assertation to argue but I would say that referenda held in controversial circumstances should not be considered valid unless independent observers report them as being free and fair.
The Russian regime now in power is not known for its interest in free and fair elections - trumped up administrative reasons why opponents cannot stand in elections, imprisonment of opponents before elections on trumped up charges, assassinations of political opponents etc,. Any referendum result in any area of Ukraine controlled by Russia has no credibility.
One problem that stems from interfering with elections is that nobody knows what voters in an election or referendum want (inevitably). And that is before the regime running the process chooses to falsify the count of votes, if it does choose to do that. For example, the declared result of the recent Venezuelan election is not believed by many people.
It helps if you have a respect for elections in your society. In the UK less than 50 people were accused of cheating in the national elections (in 2019, I think). No photo ID was required to vote, making cheating relatively easy. More than 25 million people voted.
PS I guess the best way to ensure that the number of votes recorded is accurate is to have an international agency in control of the boxes in which votes are cast, in control of counting the votes in isolation and in control of declaring the results. I would have no objection to that happening in my country.
