That the United States' intention to confront Russia over Ukraine, a place where it has no real interests, borders on the incomprehensible has been clearly demonstrated by both Scott McConnell and Daniel Larison. University of Chicago Professor John Mearsheimer has also described in some detail how the dangerous confrontation is largely the fault of Washington and its European allies, most notably because of the thoughtless expansion of NATO that genuinely threatened Russia. Former Polish President Lech Walesa, whose county would be the front line in any armed conflict, has warned that arming Ukraine might reignite the cold war and possibly even lead to a nuclear exchange.
Particularly at times when security-based policies appear to make no sense, as a former intelligence officer I am often asked how the people who work for the State Department, CIA, and DIA feel about such developments. It is a difficult question to answer as there is no such thing as a monolithic viewpoint in any of the organizations in question. On one hand, dealing with crises in international relations in one form or another is the raison d'etre of the various bureaucracies, so many are attracted by the challenge.
