- IDEA 1 OF 8
Maps explain world politics
Marshall argues that geography, including mountains, rivers, seas and climate, shapes what nations can do and what they fear.
Leaders make choices, he says, but they are always working within the limits set by the land around them.
- IDEA 2 OF 8
Russia fears its open plains
Russia faces the vast, flat North European Plain to its west, which invaders have crossed many times.
Marshall argues that this explains Russia's desire for buffer zones and its interest in warm-water ports.
- IDEA 3 OF 8
China protects its heartland
China's core is surrounded by regions like Tibet and Xinjiang, which act as buffers.
Marshall argues that controlling these areas helps China protect its heartland and water sources. Geography drives its policy.
- IDEA 4 OF 8
America has natural advantages
Marshall argues that the United States is blessed with fertile land, navigable rivers and oceans on two sides.
These advantages helped it become a superpower with few close threats. Nature favoured it.
- IDEA 5 OF 8
Europe's rivers shaped its history
Marshall describes how Europe's many rivers and plains supported trade and growth but also divided it into many nations.
Geography helps explain both its wealth and its wars. Borders followed the land.
- IDEA 6 OF 8
Africa's geography poses challenges
Marshall explains that Africa's rivers often have waterfalls that block shipping, and its coastlines have few natural harbours.
These features, along with colonial borders, made development harder. Nature and history combined.
- IDEA 7 OF 8
Mountains shape South Asia
Marshall describes how the Himalaya separates India from China, and how geography shapes tensions between India and Pakistan, including over Kashmir and water.
Rivers that cross borders add to the tension between them.
- IDEA 8 OF 8
The Arctic is a new frontier
As ice melts, Marshall argues, the Arctic is becoming a region of competition for shipping routes and resources.
Geography is creating new opportunities and conflicts. Climate is redrawing the map.
