สรุป	Comparative Foreign Policy (CFP) analysis explains the foreign-policy behavior of states by opening the 'black box' of decision making and comparing how foreign policy is produced across countries, leaders, and contexts. Part of the broader Foreign Policy Analysis (FPA) tradition that Valerie Hudson (2005) characterizes as actor-specific theory, it draws on factors at multiple levels — individual leaders, small groups and bureaucracies, domestic society, and the international system — to account for why different states (or the same state at different times) behave as they do. Its hallmark is the systematic comparison of decision processes and outputs.	Two-level game analysis is a framework introduced by Robert Putnam in 1988 for understanding how international negotiations are jointly shaped by bargaining between governments and the need to win domestic approval. A negotiator plays simultaneously at two tables: Level I, where states bargain over an agreement, and Level II, where that agreement must be ratified by domestic constituents. The key analytic device is the win-set — the set of Level I deals that could secure domestic ratification — and an agreement is possible only where the negotiating states' win-sets overlap.
