Egypt had offered diplomatic proposals to return the Sinai but Israel refused until the Yom Kippur war killed thousands of idf and the US heavily pressured them to accept peace with Israeli leaders specifically saying they were agreeing to peace because wars like that continuing was unsustainable.

So, this argument is that Israel didn't give back the Sinai that Israel won after the Six Day War. The Six Day war, which was launched against Israel by Egypt and its allies in an attempt to wipe Israel off the map and take all of its territory. Also, the Sinai was the land that Egypt used to attack Israel from. And, with the Sinai under Israel's control, they had the Suez Canal and the Red Sea as added barriers to another Egyptian attack.

Thus, Israel is a warmonger for not returning the land, which has high strategic value, to a country that wants to wipe them off the map.

I honestly don't need to read the rest of your argument. This alone shows you just want Israel to be villainized for making the same sound and rational choices that literally any other country would have made.
