“Afghanistan has no resources, has no treaties with the U.S., no historic ties, there are none of the flimsy but popular excuses that we have used for over a century to throw our weight around across the earth. But here we go, intervening anyway, loudly proclaiming that Russia’s actions in Afghanistan are ‘unacceptable’, and for which we are ready to scrap SALT, detente, and the feeble past attempts of the Carter administration to shuck off the Cold War. The conservatives, the Pentagon, the Social Democrats, the neo-conservatives, the Coalition for a Democratic Majority [..] have been yearning to smash detente, and to accelerate an already swollen arms budget and heat up the Cold War.”
