"Though he never actually joined it, he was close to some civ..." — Christopher Hitchens quote meaning

Though he never actually joined it, he was close to some civilian elements of the Democratic Front for the Liberation of Palestine, which was the most Communist (and in the rather orthodox sense) of the Palestinian formations. I remember Edward once surprising me by saying, and apropos of nothing: 'Do you know something I have never done in my political career? I have never publicly criticized the Soviet Union. It’s not that I terribly sympathize with them or anything—it's just that the Soviets have never done anything to harm me, or us.' At the time I thought this a rather naïve statement, even perhaps a slightly contemptible one, but by then I had been in parts of the Middle East where it could come as a blessed relief to meet a consecrated Moscow-line atheist-dogmatist, if only for the comparatively rational humanism that he evinced amid so much religious barking and mania. It was only later to occur to me that Edward's pronounced dislike of George Orwell was something to which I ought to have paid more attention.
