Friendly? They are in war!

Have you checked the latest events in the east Ukraine? There is a war going on there.

Long story short; EU is trying to bait Ukrainian people by giving them hopes to join EU one day. (which  is most likely not going to happen btw) In return; they want Ukraine to cut off their relations with Russia.

Russia don't like that. Not just that, some Ukrainian people also sees how they are being cheated by  EU, so they don't like that neither.

That's why the country is divided.
