The term ""searching analysis"" may cover this glibly enough, but the actual theme is harder to pin down. It consists in the delineation of a new conservative power bloc which, in part, gives an outlet to the repressed, never sublimated energies of prewar isolationists; in part, the bloc which also serves as restorative to the political ego so traumatized by the Communist triumph in China. Graebner at the same time, and with far greater concern, examines the total alignment and interplay of all conservative groups influencing foreign policy ever since the decline of bi-partisan policy under the Eisen-hower regime. The ""new isolationists"", according to Graebner, continue portions of the Truman policy, such as aid to Europe and ""committing American troops to natives threatened by attack"". But the drift is toward economic contribution and a gradual withdrawal of international cathexis. The under-lying concepts are these: the fall of China was not proof of America's inability to control world affairs, but was caused by internal corruption, especially Communist infiltration in the top levels of diplomacy (this the magic balm applied to our wounds by McCarthy). America, these ""new isolationists feel"" is invincible once it cleans house. Communism will be kept at bay from without and within; American power, in some undefined sense, will lead to the world overthrow of Soviet rule. Experts in this field of foreign affairs will appreciate Graebner's sometimes plodding but often bold approach.
