I am not going to get into whataboutism- The USA has their faults and the issues outside the white house you mention were committed by wannabee autocrat Trump.
It wasn't a coup- and it is questionable that Yanukovich was legitimately elected considering he jailed his political opponent.
And even IF it was a coup (which I don't agree it was) Russia (Putin) IS THE AGGRESSOR here- just as he was in Georgia and Chechnya- no amount of propaganda from you or others of your view can cover up for the fact that Russia has NO right to invade a soveriegn neighbor and try to take territory. Russia still occupies parts of Georgia
