It’s actually not a civil war. It’s Russia invading a sovereign nation.
Ukraine has played this role before, Russia has always wanted to control Ukraine, and Ukraine has always fought for it’s own freedom.
It’s really that simple.
Well Ukraine had always been Russia in the past.....regardless of their independence many there are Russian especially in the Eastern areas. And because it’s on Russia’s border it has always been influenced with and by Russia.
Ukraine will always be fighting at one point or another.....the citizens are unable to stop the musical chairs of the powerful in their country who continue to sell them out. Additionally you have two different cultures within the state who have never gotten along for long.
Most countries who have two distinct cultures always have conflicts....but if the ‘location’ of the nation is significant, and or it’s ‘resources’ you will always also have outside nation leaders playing it like a ball in a tennis court.
