As baseless excuses go for similar past expansive actions this one seems consistent. So Israel does the following after Palestine is recognized and accepted into UNESCO. I'll leave it to some of you to look up the evil objectives of UNESCO, balance the relative values, compare relative physical strengths and weight cultural fear against a cultural vacuum while I leave to others to fire from behind a Maginot Line. There is only an indefensible Zionist expansion wrapped loosely in legitimate security concerns and manifest against an occupied people. Starving a society because of a political affront is pathetic and Israel, of all nations, should be ashamed.
