Robert C. O’Brien’s collection of essays on US national security and foreign policy, with a foreword by Hugh Hewitt, is a wake-up call to the American people. The world has become steadily more dangerous under President Obama’s “lead from behind” foreign policy. The Obama administration’s approach has emboldened our adversaries and disheartened our allies. Indeed, Obama’s nuclear deal with Iran is a 1938 moment. At the same time, the US military has been cut and risks returning to the hollow force days of the 1970s. O’Brien lays out the challenges and provides the common-sense “peace through strength” solutions that will allow the next president to make America great again.
