A rift between Cameron and Osborne, eh?
With no Election until 2010, how could a very Noughties foreign policy be "more modern" than one which eschews such decidedly unconservative concepts as coercive utopianism, world government, and the use of "realist" as a term of abuse, and which instead takes into account the re-emergence of multipolarity and multilateralism from Moscow, to Tehran, to Caracas, with several more to follow in the near future?
Even George Bush now accepts these as the facts of life, and is behaving accordingly. So Osborne is a throwback even now, never mind in 2010 and beyond. By then, he won't even be dangerous. He'll just be ridiculous. Indeed, he already is.
