Not living in America, and not bing close to US domestic politics, I obviously can't speak to Buchanan's current level of influence or credibility, or even where he is coming from politically, except insofar as it is from some very conservative place.

However his criticisms of Scheunemann seemed to me to be consistent with the realist school of international relations - that Nations should act in their own self-interest - and that Scheunemann's activities were tantamount to Treason because they were encouraging the US to put its lives and treasure at risk in the interests of a rather rash regime in Georgia, which arguably has no great democratic legitimacy even in Georgia, and certainly no great claim the American loyalty except perhaps on the basis of the "the enemy of my enemy is my friend".

It has been characteristic of the neo-con project that the US Government has been suborned to act in the interests of a small commercial/political/industrial and military elite - and not in the interests of the US as a whole.  Surely, in that context, a return to real politique is an improvement?
