It was one of the first things Hitler did. The invasion of Poland in 1939 was a result of the “lebensraum” policy. It means that the German people needed more “living room”, Which is exactly what’s happening in Israel and has been for decades. Fun fact, one of the failures of the US and the allies at the beginning of WW2 was the appeasement policy. They felt like as long as they just gave him what he wants then there won’t be any more problems. I feel like I see a lot of that same BS here as well.
