Is the current punitive campaign against Hamas in Gaza political?

(Americanthinker).The Obama Administration wants a Leftist prime minister in Israel, someone who is pliable and willing to make major territorial concessions to the Palestinian Authority. That means either Ehud Barak, who led the retreat from Lebanon in 1992, or Tzipi Livni. They represent two parties of the Left, which could form a majority coalition in the Knesseth. One reason why the punitive Gaza strikes are taking place right now is that Obama and Hillary don't want a Bibi Netanyahu right-of-center coalition. The Gaza campaign will strengthen the Left in Israel, or that is at least the calculation.
