Scott McConnell is the executive editor of The American Conservative. A Ph.D.in history from Columbia University, he was formerly the editorial page editor of the New York Post and has been a columnist for Antiwar.com and New York Press. His work has been published in Commentary, Fortune, National Review, The New Republic, and many other publications.
I must say that his vita doesn't make him the most credible of conservative voices, mostly because of that association with the New York Post. Weigh his words against his background, that's the best anyone can do when evaluating the credibility of a source.
