CONGRESSIONAL INVESTIGATION OF AMERICAN FOREIGN-POLICY - IRAN-CONTRA IN PERSPECTIVE

Some argue the Iran-Contra investigations were inadequate, and that Co ngress shirked its constitutional responsibilities to expose the affai r. Others charge Congress expects ''another Watergate'' in every parti san controversy. Neither claim establishes realistic expectations for congressional foreign policy investigations. This argument establishes a comparative framework for evaluating important Cold War investigati ons. Three primary dimensions shape their nature, scope, and outcome. Periods of ''emergency'' or stability in the international system affe ct Congress's likely deference to the president. The institutional div ision of foreign policy powers has cumulatively favored the expansion of presidential power during the Cold War, and formidable presidential advantages limit congressional investigations. Political culture tugs in conflicting directions. American ''exceptionalism'' promotes the e xpansion of presidential power, while liberal concerns for limiting st ate power are expressed in efforts to reassert Congress's foreign poli cy role. Because congressional assertiveness is a variable phenomenon, the nature, scope, and purpose of its investigations will differ in e ach case.
