The book "The Revenge Of Geography" by Robert D. Kaplan explores how geography influences global conflicts and human behavior. Kaplan argues that the true threat to Europe is not from traditional military forces, but rather from the complex realities of refugee movements. These refugees, often fleeing desperate circumstances, pose challenges that extend beyond mere borders and demand new responses from nations.

Kaplan emphasizes that understanding this phenomenon requires a shift in perspective. Instead of focusing solely on military might, Europe must consider the geopolitical implications of large-scale migration and the social, economic, and political disruptions that can arise from it. The future of European stability may hinge on how nations respond to the influx of refugees and the underlying issues causing their displacement.
