Henehan tries to wrest this subfield away from those scholars who explain relations between the president and Congress just as a problem of American politics. She emphasizes the international trends that increase the pressure on U.S. institutions -- pressure that eventually surfaces in domestic upheavals. She marshals various methods and charts to make this evident and sensible insight plausible to her academic colleagues.

In her slim book, Hersman provides the most informative account of how executive-congressional interactions actually work. A former staffer in the Pentagon and on Capitol Hill, she outlines an "informal universe" of interaction, where personalities play a critical role, especially "issue leaders" within Congress. Interagency battles enlist congressional soldiers and the advocates, in and out of government, who cluster around particular issues. Cases on arms sales to Turkey, sanctions against Pakistan, and the battle over the Chemical Weapons Convention round out the argument, which suffers only from its inattention to the more complex world of trade and economic issues.
