The PA is running for the general assembly vote because they know in recent elections around the world that leftist anti israel politicians have been losing over their massive spending and open immigration policies. In a few years the world will have much different leadership. In france you could have a right wing leader who is very friendly towards israel. In spain you will have the anti israel government gone and a new friendly israel government in place. These leftist leaders that came to power before 2008 are now very unpopular and there will be new world leadership on the horizon and that is why PA is rushing the general assembly vote to get as strong a vote as possible before these leaders are voted out offfice. The american electorate voice gets heard finally. In 2009 we kept hearing how much america couldn't stand bibi. Wrong israel's approvals were at all time highs and it was the leftist politicians now you see how different congressional leaders that don't kiss up to the white house and bibi gets invited for a speech.
