Israel prohibits Palestinian flag in public

Israel has prohibited showing the Palestinian flag in public places.

Palestine asked the UN to adjudicate Israel's occupation of Palestine, and Israel is "punishing" this by applying many forms of repression all at once. (I have the feeling that the right-wing extremists in the new Israeli government were itching for an opportunity to do this.)

But why should Palestinians deserve punishment for asking the UN for adjudication of their rights?
