This is a correct point, of course. But the argument is even simpler: that international community has ignored 800 people killed as "collaborators" by the Palestinians; there is no need to look elsewhere. These 800 are just in the first intifada, which ended in 1993.
Just last week they murdered a "collaborator." I often wondered who these collaborators were: after all, the Palestinians may have uncovered someone who had indeed supplied information to teh Mossad. Well, last week, the killer announced to the cheering crowd that surrounded the lifeless body that "you are a collaborator if you tell a Jew [sic] the name of the steet he stands on."
Almost 1000 people have been murdered right in fron of the cameras of this international community. The answer? Not a word.
In every case, I'm afraid, western forces have only two choices---capitulate, or utterly eradicate their enemies. There is no middle ground.
