That costly and protracted wars with high levels of casualties tend to destablize all states involved, heightening social contradictions & bringing down some regimes appears to me to be one of the truths that individuals of contradictory ethical and political dispositions can recognize, be they religious fundamentalist worriers, strategists for the U.S. national security state, or Noam Chomsky, if they do not to act like an ostrich with his head in the sand (and they don't, unlike some LBO-talkers).
While (A) all of us should do all we can to prevent a U.S. war on Middle-Eastern nations from happening, it is probable (B) that we will not be able to prevent it from beginning, given objective circumstances (only one in the entire U.S. Congress voting against war; a far larger number of Americans preferring military action, even if it results in civilian casualties, than those who desire other options; marginality and disorganization of leftists in the US; US governing elite's willingness to exploit the WTC bombings to test what Americans tolerate; etc.). (A) expresses my ethical preference; (B) is my prediction based upon historical knowledge and objective analysis of current conditions. Therefore, I think leftists should think about what may result from (B) & how to respond to it, and in that spirit I've laid out several possibilities (one of which may likely doom us all, whatever we do).
Try not to be an ostrich.
