Even Yanukovich's own Party of Regions voted against him. There was no way he could have continued as president.
It's obvious you have bias to one side. It wasn't possible for voting to take place in Eastern Ukraine or Crimea, because the occupiers wouldn't allow it.
The problem this is an ethnic majority from another country which wants to break.away. A country which has more territory than any other. Do you support the independence of Kosovo? There are many ethnicities and nationalities who would like independence, how far could it go? It would mean Quebec, Basques, Catalonia, Kurdistan, Tibet and parts of Russia becoming independent amongst many others.
If a people are strong enough and have the numbers to form an army enough to hold their ground, then yes they should have their own nation.
For example, many people hate Jews and hate Israel, and call it an illegal “occupation” of Palestine. Yet they have an army able to hold it, and already have defended it against foreign attackers. Even if you hate Jews, what is wrong with allowing them to have their own nation? It would encourage Jews to move their and out of other nations. Same for Muslims. I hate Muslims, but still believe they are entitled to their own shit hole countries, and we should deport Muslims so they can return to their own shit holes instead of making Western countries into shit holes.
The new Ukraine isn’t strong enough to hold to the lands in what used to be Eastern Ukraine and Crimea. So stop crying about. Otherwise pick up a rifle and join the fight to take it back from the Russians. Until then you sound like a little ***** crying about losing a war.
