The fundamental drive of foreign policy of the core capitalist states (including the new semi-members of that core -- Russia and China) is the drive to keep the whole fucking world open to capitalist expansion, whether the frims conducting that expansion are French, U.S. China, or firms from the periphery. India is clearly a vicious capitalist state, and certainly supports the world empire of capital, but whether it is with the core yet I have no opinion.)
Ellen Meiksins Wood had several 'credentials' for providing the most powerful analysis to date of this _Empire of Capital_ (her title and the best descripton of the current world). Preeminently, she has always shown a clear grasp of the role of contingency in human history and therefore was free from the more metaphysical or mechanical Marxist theories of imperialism and of the context of capitalism within human activity as a whole. (Thus she was able to grasp Brenner's discovery that capitalism itself was an accident, not emerging from previous progressive growth (which was mostly in Asia) but from a little mud spot on the periphery of world society.)
The U.S. remains the most important disciplinarian of this world empire, though we must not forget French responsibility for the genocide in Rwanda or German responsibility for the dissolution of Yugoslavia. And of course whatever circus-performance they put on for domestic consumption are all fully-involved in the support of u.s. action around the world. (Local flare-ups between the major powers will continue, but there will be no repetition of former "World" Wars to divide the globe.
That has to be the context of theorizing by those commited to socialist revolution.
