Yes, Europe's defence budget is 4x that of Russia. If Europe stepped out of the Trans-Atlantic alliance and organised her defence (not offence as the US is currently orchestrating - leading us again to another Vietnam, Korea, Afghanistan, Iraq and Syria) Russia's reason for invading Ukraine is gone.

With that "win" in its bag, it can leave Ukraine without loss of face. Once the population is back a true referendum can be held in the Dombas under EU or UN supervision. And the best for all on our continent would be for both Russia and Ukraine to join the EU. Gorbachev and De Gaulle's vision finally come true: One Europe.
