When in 1948 the UN formulated its partition plan (i.e. the proposal to expropriate the Palestinians of half of their land to give it to the Jewish immigrants), the land that the proposal assigned to the Jewish state had a 45% Palestinian population, which the newborn state immediately proceeded to ethnically cleanse. Besides, Israel never formally accepted the borders of the partition plan and immediately set to conquer new territory (plan Dalet).
As of today, 20% of Israel population are Arabic. Compare that to how Jewish population developed in Arabic countries i.e. Egypt, with practically zero Jews left. Not saying they did ethnical cleansing, but you don't end up with 20% when doing that. We will never now how the numbers had turned out without Arabic countries attacking Israel multiple times, but for sure with more than 20%.

That's rewriting history. The initial borders and border changes happened while defending against attacks from other countries. Regarding the six day war, from what I have read, there are serious signs that support the view of the six day war being a preemptive strike.
It was meant as a western foothold in the middle east, which is clearly the case now. In a despicable manner, Germany now is aiding and abetting the atrocities committed by the colony of Israel, as if two wrongs make a right.
