I wonder who organized this event in UN headquarters. Was it UN staff? French representative in UN? Or was it Ms Le Pen with several supporters carrying signs "Occupy UN" (LOL)? So it is kosher for UN or French representative there to organize such an event but not for Israeli representative to attend it? There are many events in UN honouring such personalities that Ms Le Pen looks like a girl-scout in comparison.
