Is global military spending a necessary evil or a massive waste of resources?

This video examines why nations commit $2.2 trillion annually to defense. By applying the prisoner's dilemma to international relations, it explores whether this massive expenditure is a strategic necessity for maintaining freedom or an inefficient allocation of global wealth.

The video utilizes game theory—specifically the prisoner's dilemma—to analyze the logic behind military budgets. It suggests that the competitive nature of international security forces nations into a cycle of spending that might otherwise be viewed as wasteful.

By reframing common narratives surrounding defense budgets, the analysis questions whether the $2.2 trillion spent each year is an unavoidable consequence of geopolitical tension or a choice that could be managed differently.
