Prisoners of Geography

IDEA 1
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
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
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 1
Geography still shapes the future
In this follow-up, Marshall examines ten regions whose geography will shape world affairs. He argues that physical features continue to influence power, trade and conflict in the twenty-first century. Old patterns persist.
IDEA 2
Australia sits between powers
Marshall describes Australia's position between the United States and China. Its distance from allies and closeness to Asia create difficult strategic choices. Its choices will matter for the whole region.
IDEA 3
Iran is a mountain fortress
Iran's mountains, Marshall explains, make it hard to invade but also hard to unite. Its geography shapes its defensive mindset and regional ambitions. Its terrain protects but also isolates. Defence comes first.
