Who, apart from enlistees, had a "duty" to join in the misconceived Asian Games of 1959-1975? By 1969 it was obvious to anyone with eyes to see that the war was not going to be "won," and that the duration and nature of its prolongation would be determined by the perceived advantage to be had for the Nixon administration. Hell, avoiding Southeast Asia looks to be the single significantly intelligent act of Dubya's wastrel youth--assuming, of course (which may be a stretch), that the strategem employed was of his own devising.
