The Coming Age of Territorial Expansion

Climate Change Will Fuel Contests—and Maybe Wars—for Land and Resources
Since the mid-twentieth century, the power dynamics and system of alliances that made up the postwar global order provided a strong check on campaigns to conquer and acquire territory—an otherwise enduring feature of human history. But rather than marking a definitive break from the aggression of the past, this era of relative restraint now seems to have been merely a brief deviation from the historical pattern. From Russia’s invasion of Ukraine to U.S. President Donald Trump’s avowed interest in acquiring Greenland, international land grabs are back on the table. Threats of territorial conquest are once again becoming a central part of geopolitics, driven by a new phase of great-power competition, growing population pressures, shifts in technology, and, perhaps most crucially, a changing climate.
