Plain-language definitions for terms you'll encounter in geopolitics and international economics.
Containment doctrine
A strategy of constraining a rival power's expansion by sustained diplomatic, economic, and military pressure short of direct war. George Kennan, writing as 'X' in *Foreign Affairs* in July 1947, argued that Soviet power would expand wherever it met no firm resistance, and that a patient policy of 'long-term, vigilant containment' would eventually force the Soviet system to mellow or break under its own contradictions. The doctrine shaped four decades of US grand strategy through NATO, alliance networks in Asia, the Marshall Plan, and forward-deployed forces. Kennan himself spent much of the rest of his life arguing that containment had been militarised in ways he never intended. The framework returned in the 2010s applied to China — first as 'pivot' or 'rebalance' under Obama, then as overt strategic competition under Trump and Biden. The Quad, AUKUS, and the Indo-Pacific Economic Framework are best read as alliance architecture for a containment-adjacent posture, even when officials avoid the word. Indo-Pacific analyses on this site track that framing without endorsing it.
Hegemonic stability theory
The argument that the world economy works best when one dominant state — a hegemon — is willing to underwrite open trade, lender-of-last-resort liquidity, and a stable reserve currency. Robert Gilpin developed the political-economy version of the theory in *War and Change in World Politics* (1981); Charles Kindleberger had earlier argued in *The World in Depression* (1973) that the inter-war collapse happened in part because Britain could no longer play the stabiliser role and the United States was not yet willing to. The theory predicts that as the hegemon's relative economic weight declines, its capacity to absorb shocks for the system also declines — and the system becomes more crisis-prone unless a successor or a coalition takes over the stabilising functions. Critics, including Susan Strange and later Daniel Drezner, argue the theory overweights material capabilities and underweights the institutional and ideological work that goes into making rules stick. The framework is the analytical backdrop for current debates about whether the United States is still willing to play the role the post-1945 system was designed around — a question the *Chip War* and CHIPS Act analyses on this site both turn on.
Monroe Doctrine
A 19th-century US foreign policy stance, articulated in 1823, declaring opposition to European colonization or interference in the Western Hemisphere. Its modern legacy is shorthand for any great power claim to a regional sphere of influence.
Soft power
The ability to get other countries to want what you want, without paying them or threatening them. The pull comes from your culture, your institutions, and your foreign policy. Joseph Nye introduced the term in *Bound to Lead* (1990) and elaborated it in *Soft Power* (2004), arguing that the United States enjoyed a structural advantage because its universities, films, philanthropies, and political ideals had global reach. The framework had its high water mark in the 1990s and early 2000s. The 2020s have eaten the concept on three fronts: the Iraq war and its aftermath drained the legitimacy account; social-media fragmentation broke the unitary cultural signal Hollywood and American universities once carried; and rising powers — China's Confucius Institutes, Gulf state-funded universities, India's diaspora-based outreach — built their own soft-power infrastructure. Nye's later work concedes that hard and soft power are entangled in 'smart power', and that soft power without hard-power credibility behind it tends to evaporate when tested. The G7-G20 institutional-coordination analyses on this site treat soft power as one input among several, not the master variable the 1990s framing claimed.
