Thats simply not true
Come on, the tunnel system is something even Hamas is boasting about...
Expelled/cleansed Germans did have a state(s) to retreat to.
Many of those never held German citizenship before and there was most definitely no German state to return to in say 1946. The people going to Flensburg, Saarbrücken or Aachen could not be certain that they would live in Germany in the future.
comparison between post war Germany and Palestine is not a valid equivalent
It is, because the similarities are striking. Both had lost territories due to a war they started because they could not accept the loss of territory. They had to live on less land than before, which was also poor/destroyed. The expelled people dreamt of their return.
But the Germans were fortunate enough to have leaders that cared for their people, particulary in West Germany. And who were brave enough to tell them that their dreams of return would never come to pass. The Palestinians needed a Willy Brandt, but all they got was Arafat and from then it went only downhill.
Germans got their reunified state after Kohl confirmed that Breslau, Stettin and Königsberg would never again be part of Germany. And we lived very well afterwards, even though Putin's imperialism is now throwing long shadows (while also showing how damaging clinging to the past really is).
The Palestinians will have their own state once they come to terms with the fact Jerusalem and Tel Aviv belong to Israel.
