The Bible tells how God decided to obliterate Sodom because of the wickedness of its people (Genesis, 18). The legend gives us an example of this wickedness: the special bed for visitors. When a stranger came to Sodom, he was put in this bed. If he was too tall, his legs were shortened. If he was too short, his limbs were stretched to fit.
In political life, there is more than one bed like this. On the Right and on the Left, there are people who put every problem in such a bed, cut off limbs and stretch limbs, until reality matches theory.
From the sixties on, doctrinaire leftists tended to put every situation into the bed of Vietnam. Everything - be it the murderous tyranny in Chile or the American threats against Cuba - had to fit the Vietnam example. Applying this model, it was easy to decide who were the good guys and who the bad, what to do and how to solve the problem.
That was convenient. It is much easier to draw conclusions when there is no need to consider the complexities of a particular conflict, its historical background and its local circumstances.
