Its absurd even if you dont count the interveneing time frame..
Why is that incident the "cause but not the attacks accross the border that incited Israel to invade lebanon..or how about the 67 war or the 48 war...basically you could go all the way back to the founding of Israel when teh Arab countries attacked them COMPLETELY without provocation.
One incident in 2000? it would be laughable if it wasnt so pathetic.
