Christopher Flannery - Classics of Strategy and Diplomacy

Mahan, Choke Points, and the Panama Canal

April 02, 2021

The recent blockage of the Suez Canal by the container ship Ever Given is a reminder of the importance of maritime choke points as they concern international commerce and national security. Choke points are primarily the effect of natural geography, which is one of the critical dimensions of strategy. In some cases, however, human agency, especially technology, can affect the strategic importance of natural geographic features and relationships. The shift from sail to steam, then from coal to oil-fired ships. From roads to railways. From horses to internal combustion engines. From the ground to the skies — aircraft to ballistic missiles, to drones, and hypersonic vehicles. Another human agency is the construction of canals in a way that significantly alters the geopolitical terrain.

Of Geography and Politics

Christopher Flannery

If statesmanship or the political art is synonymous with the art of war or the art of acquisition on the grandest scale, then mastery of geography becomes "the first part" of the statesman's arsenal. "[H]e should learn the nature of sites, and recognize how mountains rise, how valleys open up, how plains lie, and understand the nature of rivers and marshes—and in this invest the greatest care.… And the prince who lacks this skill lacks the first part of what a captain must have." If the "desire to acquire" or the "lust for power" is inherently unlimited and is the governing principle of politics, then the primary concern of politics with geography, the concern with acquisition of territory, in principle knows no bounds. The concern of politics with geography, at a certain point in history, expanded its scope, not just in principle but in fact, to encompass the world.
