1) there had been a legitimate transfer of power when majority in the Parliament removed Ya. from power.
2)change in government doesn’t nullify all previous treaties, especially something as basic as non-aggression. Diplomatic treaties exist between states not governments which were in power the moment a treaty was signed. When there’s a new president, does that nullify NAFTA, START, American leases abroad, security commitments abroad, contracts, debts or loans? Of course not, that’s that’s the ridiculous part.
If Russia can’t commit to a non-aggression treaty with the new government, why should Ukraine transport Russian gas, honour whatever debts it might have, allow airplanes to fly over, or not kick every Russian company out of Ukraine.
Putin BROKE the Budapest Memorandum and he’s perfectly entitled to do it. Just accept what comes with the label “can’t keep your word” and don’t insult people’s intelligence saying that you get carte blanche when there’s new government.
The Ukrainian Constitution has very specific rules for Presidential impeachment, and a majority vote in parliament isn't one of them. Neither is mob rule.
Keep trying donkey.
