Alfred Thayer Mahan
Prophet of Sea Power
A mediocre sailor who hated the sea wrote one book that launched a global naval arms race. Mahan's theory still drives strategy from DC to Beijing.

Classical Theorists (pre-WWII)
Halford Mackinder
Father of Geopolitics
In 1904 a British geographer argued whoever controls Central Eurasia controls the world. Mackinder's Heartland Theory invented geopolitics as a discipline.
Hans Morgenthau
Father of Modern Realism
A refugee from Nazi Germany who made power politics into a science. Morgenthau founded modern realism, then wielded it to oppose the Vietnam War.
Henry Kissinger
The Architect of Realpolitik
He opened China, pursued detente, and stands accused of war crimes. Kissinger's century-long career defined realpolitik and its moral contradictions.
Kenneth Waltz
Architect of Structural Realism
Waltz stripped international relations to a single variable: the system's anarchic structure. His neorealism became the theory every rival had to answer.
Nicholas Spykman
Architect of American Grand Strategy
He died in 1943 before seeing the Cold War he predicted. Spykman's Rimland theory flipped Mackinder and became America's containment blueprint.
Sun Tzu
The Master of Strategic Thought
Where Clausewitz saw war as politics by violence, Sun Tzu called violence strategic failure. His Art of War still shapes how China projects power today.
Thucydides
The Father of Political Realism
An exiled Athenian general wrote the first analysis of power politics 2,400 years ago. His Athens-vs-Sparta account still frames how we see US vs. China.
Modern Strategists (post-WWII)
Alexander Dugin
Called 'Putin's brain,' Dugin built a neo-Eurasianist ideology that frames Russia's wars as a civilizational struggle against the liberal Atlantic order.
Carl Schmitt
A Nazi collaborator whose ideas neither left nor right can stop using. Schmitt's friend-enemy distinction still defines debates on sovereignty and power.
Carl von Clausewitz
He never won a decisive battle and died before finishing his book. Yet Clausewitz's On War defined how the West thinks about conflict for two centuries.
Francis Fukuyama
He declared liberal democracy the final form of government as the Cold War ended. Three decades of democratic backsliding later, his thesis still provokes.
George Kennan
One telegram from Moscow in 1946 launched America's Cold War strategy. Kennan then spent decades opposing the militarized containment his words inspired.
Graham Allison
He used the Cuban Missile Crisis to expose how governments actually decide, then coined 'Thucydides Trap' — the framework dominating US-China analysis.
John Mearsheimer
He warned that NATO expansion would provoke Russia long before Ukraine. Mearsheimer's offensive realism makes him the most debated IR scholar alive.
Joseph Nye
When everyone declared America in decline, Nye argued they measured the wrong thing. His 'soft power' concept redefined how nations think about influence.
Robert Keohane
Keohane accepted realism's bleak premises, then proved cooperation could emerge from anarchy. His institutionalism became the main rival to power politics.
Samuel Huntington
His 'Clash of Civilizations' predicted wars along cultural fault lines, not ideology. Praised as prophetic or condemned as bigotry, it shaped a generation.
Zbigniew Brzezinski
A Polish exile who became Carter's national security advisor and mapped Eurasia as the grand chessboard where American primacy would be won or lost.
