Mearsheimer has argued that NATO “caused” Putins invasion of Ukraine. Please explain why that is “right” even partially. & spell out what evidence would falsify your hypothesis. https://t.co/akqHwtzgS5 Quoted tweet from @alxgraef: Mearsheimer is right but simply incomplete. Structural factors do matter but they cannot explain all outcomes. Same is true for explanations based on personality or political regime. Theories are not reality. They all tell only part of the story. Some more, some less.
