Oh, you just wanted the definition to explicitly include the Nazi consequence. I agree that the wiki article could’ve done better in this way.

People worldwide are way dumber than you’re assuming. But, I think that one of the best things we can do about that is to communicate as if they were intelligent.

I expect that a small minority of people would learn what lebensraum was and the context that it was an essential part to the fascist Nazi party. I also expect that those people would perceive the metaphor and understand why both it and Israel’s actions are wrong and evil.
