No US president can possibly afford to pressure israel into allowing a palestinian state if Islamic terrorists like Hamas are involved. Probably not much chance of a palestinian state vert soon anyway, but this would kill it for sure. It doesn't matter if it is Bush or Hilary, US president could not politically survive it they dealt Hamas or tried to force Israel to deal with Hamas. Palestinian people have a choice-nationalism or islamicism. Until they totally reject islamicism and acccept secular nationalism, there will be no palestinian state in the current lifetime of any palestinian.
