There was a similar moral deficit when it came to foreign policy. The xenophilliac 68ers, could by and large, never grasp that there were two competing truths about Vietnam. Yes, we, the Americans shouldn't have been there. But yes, the Communists were brutal thugs. When after the war had ended and a million and half people went into the sea to escape the regime of the North Vietnamese Stalinists, the famously voluble moralising associated with the 68ers was replaced by sustained silence. Today, aided by the Bush administration's extraordinary meld of simple mindedness and incompetence, the 68ers are similarly unable to come to grips with Jihadism. Too self-absorbed to be self-reflective, they both denounce the neo-conservatives for assuming that everyone wants freedom and democracy, yet insist that we can negotiate without conditions with terrorist regimes on the grounds that we share a great deal in common.
