Israel is not "occupying" Gaza. Israel is not even IN Gaza, since 2005. Israel is regularly attacked by Gaza. Israel provides water and electricity to Gaza, when Gaza pays for it. Who else provides that to an entity it is at war with?

Israel has no responsibilities to Gaza any more than Egypt does.  Yet it actually provides more than Egypt.

And you use the term "Palestinian Israels".  You might want to learn your history.  Before 1947, Arabs, Jews, Christians, Greeks, Armenians living in British Mandate Palestine were all "Palestinians".  The predecessor to the Jerusalem Post, an English-language newspaper owned and run by Jews, was called the Palestine Post.  When the state of Israel was formally created, its citizens were Jews, Arabs, and others.  So if you want to call those Arabs Palestinians, why not call the Jews Palestinians too?  The term could be (and has been) transferred to Arabs not in Israel, which is fine.
