Please remind me quickly, who invaded who already? Germany what? Maybe in 1939, but definitely not in 2014. And there was no Ribbentrop-Molotov pact between Merkel and Putin, let's stop inventing things for the sake of an imaginary argument. So on short: Russia invaded the Ukraine because why not, the Eastern Europe and more is now on fire thanks to that, and I must read here funny numbers and how Russia doesn't like sanctions (duh, that's the whole point of sanctions).
