What do the classic theories say?

Mackinder argued that whoever controls the Eurasian "Heartland" commands the world. Mahan countered that sea power is what makes great powers. Spykman said the real key is the "Rimland"—Eurasia's coastal edge, including Western Europe, the Middle East, and the Korean Peninsula. US Cold War containment drew heavily on Rimland thinking.

Why does geopolitics matter now?

Roughly a fifth of the world's oil passes through the Strait of Hormuz, and the Taiwan Strait sits at the heart of semiconductor supply chains, so tension in either can instantly move oil prices, currencies, and stock markets—what investors call geopolitical risk. The Korean Peninsula, where continental and maritime powers meet, has long been a stage for great-power rivalry.
