Nobody is trying to force Ukraine into the EU. Ukrainians want to join the EU but the EU will not let them. The conflict between Russia and Ukraine has happened because Ukrainians do not want to be Russia’s slaves.
You are very incompletely informed. Did you even read about this region before the Russians moved into Crimea? Moreover, Talking as if “Ukrainians” have uniform views is ridiculous.
The strong do what they can, the weak do what they must.
