Wars can be waged at home or thousands of miles away. They can be fought from the air, or down in the trenches. They can be over in months, or can last years – but one thing wars will never be is cheap. From the economic and environmental costs, to the social and human impacts, this fascinating series takes a forensic look at the mechanics of war to discover the price that must be paid – and who will ultimately pay it – when our leaders choose conflict over peace. Combining dramatic recreations and archive footage with insightful interviews and cutting-edge graphics, each episode explores, investigates and exposes a different conflict. From the two World Wars and Vietnam, to more recent wars in Afghanistan, Iraq, and the global War on Terror, we see how the costs escalate and accelerate as each conflict develops.
