By all accounts and reports, it appears fatah and hamas are on the verge of full scale war with each other. This may be more vestiges of history than the raw conflict of grabbing for power since vested interests go way beyond the triangle of the US, Israel and the palestinians, whoever the latter might really be. I doubt the loyalty and committment of neighbors to the 'palestinians' has changed one bit and they are still aligned with the same players despite the infighting. Personally I think Israel's traditional and historical culpability is somewhat exonerated in light of the serious escalation between hamas and fatah.
