I'm not sure the Senator ever described himself as "altruistic". He had goals, but knew when to make a deal. Compromise is the normal outcome of political debate.Generally more than two, and some have a firmer basis in reality than others.
I never suggested he should serve Palestinians, but rather simply pointing out that his service to the conquest of their homeland in violation of international law undermines the claim of altruism. I have yet to see a reasonable argument that he did so for the interests of us Americans either, at least aside from for the few who have built an industry around this conquest. If you are suggesting otherwise, I am interested in seeing how you substantiate your perspective.
