It has to do with keeping a single standard
Except what ever standard you're trying to set doesn't track with the hypothetical set.
Again, hypothetical is if Israel left the occupied land( West Bank & Gaza) would it be justified for Palestinians to want the entirety of Israel? You said yes. What ever hypothetical you bring, if you want to make a comparison has to be similar to the hypothetical set.
It was also rather a rhetorical question. Why would the korean and chinese be lenient if japanese started to migrate as it means more japanese illegally occupying their land. Implying they would have stopped their resistance is a no brainer
Again, back to the hypothetical
if Israel left the occupied land( West Bank & Gaza) would it be justified for Palestinians to want the entirety of Israel?
Your rhetorical question just doesn't apply here. Like I've said, in the 1950s/60s? yeah sure. Now? No. There's millions of ethnic Israelis in the land.
Like I've said before. The correct question is "If Imperial Japan after annexing Korea and Manchuria decided to move millions of ethnic Japanese people and present day are the super majority of the land, would it be justify for koreans or chinese people to try to reclaim that land in 2023?"
And I've already said no, that is ridiculous.
If Israeli starts to move out of Palestine but the military establishments, nothing will change.
Obviously the hope is each side stays on their own side
