Query: Foreign policy wisdom

A Republic, Not an Empire is Pat Buchanan's masterful tome on the dangerous course of American foreign policy.As the United States remains the "sole superpower" in the world, it is setting a course for its own ruin, much like Rome and Britain, by becoming entangled in countless foreign wars and intrigues.Much of this books reads like a history primer, illustrating how America wisely avoided, or was forced into international conflicts until the Cold War, when the threat of international Communism forced us to become a military and industrial power.Buchanan's writing and philosophy demand reader's attention and intelligence, which is probably why the typical leftists and neocons hated it, instead falsefully accusing it of anti-Semitism.Perhaps Buchanan will be heard, before it's too late.
