Not wanting to piss all over your bonfire of all knowing enlightenment, Udie, but this constant 'the UN is biased' whine is a little tiresome. For one thing, a UN resolution created Israel in the first place. Or does your knowledge not stretch that far back in time?
Now, the Jenin action was condemned by Israel's staunchest ally, the US. Yet you still insist Israel was in the right?
In reference to the 'military advisors' - why do you need them to count bodies? I think it was more a question of Israel snubbing the UN at any cost, over the slightest issue.
Finally, what you singly fail to understand, Udie, is that Israel has to tread carefully in respect to US opinion. It can't go in hard (although I'm sure people like Sharon would be positively orgasmic at the prospect), because that would upset the US and Israel relies on the US for its existence. Consequently, nuking the West Bank would be a bad move.
Instead it pursues a course of settlement and containment to achieve lebensraum.
