I moved this from below for convenience I ve removed discussion of the Palestinians and the Palestinian Liberation Organization from the background I believe a brief historical background which included the history of Palestinian militancy would need to include some mention of what they were fighting for so as not to introduce an anti Palestinian POV However any mention of the Palestinian refugee camps in Lebanon is consistantly deleted from the article with the claim that it is not relevant to this conflict So I will wear a black hat and ensure a more restrictive view of relevancy to the background and edit appropriately
