Maybe the Israelis aren't as dumb or naive as I had first feared. This excerpt from a recent Strategy Page article explains Israel's current overarching strategy towards its Palestinian adversaries, which connects the dots and goes a long way to explaining the bits and pieces the MSM usually picks up.
Israel's Palestinian enemies--although grouped into many arcane factions--are currently organized into two main parties--Hamas and Fatah. Israel's ongoing strategy is a variant of the tried-and-true 'divide and conquer' gambit. Instead of fighting both groups at the same time, Israel is playing one off the other, which weakens both and is easier than fighting a unified foe.
The article is aptly titled "Deal with the Devil." Rest assured, whether its Fatah or Hamas, that's exactly what you're dealing with:
The growing war between Hamas and Fatah has presented Fatah with the option to turn on terrorist groups, and form an alliance with Israel. This is seen as the only solution to the dozens of West Bank Israeli checkpoints that slow traffic to a crawl, but are considered essential in limiting the movement of Palestinian terrorists. Fatah, however, has been spouting "hate Israel" propaganda for decades, and turning kind and gentle would split the organization. But Fatah is being forced to ally itself with Israel, because Hamas operatives in the West Bank are apparently under orders to destroy Fatah there any way they can, and take control. This involves the use of Islamic radical death squads, that murder Moslems for not being Moslem enough, and Arab Christians for not being Moslem. Thus Fatah is fighting for its life, and making common cause with Israel whether it likes it or not.
