The author, as always, sees the deeper scenario behind the public display of politics in the US.
What Woodward's book - and the corporate media orchestrated narrative - will never tell is "why" infinite war. Because of the New Great Game in Eurasia. Because of the need of military bases to spy on strategic competitors Russia and China. Because of the US's obsession with Pipelineistan in Central Asia bypassing both Russia and Iran. Because of the Pentagon's full spectrum dominance doctrine - which justifies infinitely ballooning military budgets.There appears to be a split between Obama (and probably some segment of the US ruling class) and the military establishment (and no doubt other aggressive imperialist-minded hawks, Zionists, etc.) Whatever the outcome of this contest, it is rare that such internecine conflicts among capitalists result in any long term benefits for working people.
Thus I do not agree with the optimistic outlook of American liberal Tom Engelhardt as indicated by his piece entitled, "Why the troops are coming home". He provides a good historical background of US involvement in Eurasia, but doesn't seem to see US involvement as it should be seen--imperial involvement in The Great Game of Eurasia. Escobar does. Therefore, I would have to bet against Engelhardt and his optimistic prediction of US volunteer withdrawal.
