The US and Israel are discussing ways to effect the collapse of the Hamas government, so a new election will be called. In other words, they will be using collective punishment. All Palestinians will be punished because they democratically elected Hamas. They just can't win, can they? Notice how this New York Times article used the word "starvation" several times but it was too coy to use it in reference to the people, only to the government.
The question is: would Fateh cooperate with these plans? Rumors are that they will not participate in a Hamas government, which might indicate that they indeed are collaborating. But so far it's just a rumor.
