“....they will be welcomed with open arms and flowers.”

The Nazis were initially welcomed in the Ukraine in WWII but, stupidly, they showed their ingratitude.
Had the Nazis incorporated the Ukraine in a more honorable way, the two nations would have conquered Russia and the people in Europe would all be speaking German.
Oh, they would have incorporated Ukraine, all right...by using it’s occupants as fertilizer.
Hitler wanted to colonize the fertile grain-producing areas of Eastern Europe with Germans. That would be at the expense of Poles and Ukrainians.
That some Ukrainians initially welcomed the Germans was because of how badly they had been treated by Stalin (upwards of 3 million killed by starvation thanks to his policies in the 1930s), and perhaps ignorance of what the Nazi ideology was. It might have made sense for Hitler to treat the captive nations of the USSR well, but it would have gone contrary to his ideology. From a practical perspective, the Holocaust itself was stupid--killing healthy productive people for no reason beyond an obsession in Hitler's own mind.
