anti-war activism

His films *Dr. Strangelove*, *Full Metal Jacket*, and *Paths of Glory* systematically deconstruct the absurdity, machinery, and human cost of warfare through dark satire and unflinching realism.

His meditative masterpiece *Mirror* and philosophical approach to cinema explore the spiritual devastation of war and violence through poetic, introspective cinema.

His documentarian style in films like *The Wind That Shakes the Barley* and *Kes* presents humanistic critiques of militarism, imperialism, and systemic violence affecting ordinary people.
