摘要	Content analysis of political speeches turns the public words of foreign-policy actors — leaders' addresses, UN General Assembly statements, parliamentary debates, press briefings — into systematic, comparable measures. Spanning classic human-coded content analysis and modern text-as-data methods surveyed by Grimmer and Stewart (2013), it lets researchers quantify what leaders say: their threat perceptions, hostility, cooperative or conflictual orientation, issue priorities, and rhetorical positions, so that rhetoric can be tracked over time, compared across actors, and related to behavior.	Operational code analysis measures a political leader's belief system — their fundamental assumptions about the nature of politics and the best strategies for pursuing goals — from the leader's own words. Originating in Nathan Leites's study of the Bolshevik mindset and reformulated by Alexander George (1969) into a structured set of philosophical and instrumental questions, it later became a quantitative method through the Verbs in Context System (VICS). By coding how a leader talks about conflict, cooperation, control, and risk, analysts characterize the cognitive framework through which that leader interprets the world and chooses action.
