The reason the Palestinians are having problems is that they've been fighting everyone (including themselves) for the last seventy years.

They tried to wipe out Israel, failed, tried again, failed, tried to take over Jordan (in a show of beautiful irony people are curiously reticent to talk about), failed, tried one last time to wipe out Israel, failed, then tried to take over Lebanon - and - can you guess? Failed.

At no point during any of this have they conducted peace negotiations during which they actually stopped attacking. While they were sitting around the table at Oslo talking about stopping violence they were literally the same day firing mortars and rockets into Israel.

I mean, there is exactly one plausible path to peace which hasn't already been tried, and it's so blindingly obvious it amazes me that it's escaped the notice of so many apologists, but has it occurred to you that if the Palestinians collectively could just stop attacking Israel for an extended period (six entire months, say - out of seventy years) then there might actually be a climate conducive to a proper settlement?
