Sarah Paine - Why Putin and Xi can't escape geography

In this lecture, military historian Sarah Paine lays out the geopolitical framework that has shaped global power for two thousand years: the divide between continental empires that pursue security through territorial conquest (China, Russia) and maritime powers that pursue prosperity through trade (Britain, the US). Recorded first in Paine's 2025 series, this is the framework that all her other lectures build on.
