There is a difference between Gaza and Palestine. Palestine consists of Gaza (from Egypt), the West Bank (from Jordan), and the Golan Heights (from Syria).
Israel is only at war with Gaza which is led by Hamas. The other two are led by the Palestinian Authority - not Hamas.
Gaza is not oppressed. It never has been. What it is no longer free to do is send in suicide bombers - not since Israel built the border wall. Why did Egypt build an even higher wall?
