Being a superpower is not what it used to be. These days, you can do it on a shoestring.

A superpower is a country able to project its military power over great distances and, if necessary, fight more than one war at a time – and in different continents. That costs a lot of money: military bases, ships, aircraft, tanks, missiles, communications and transportation infrastructure, none of this comes cheap. Also necessary is an expeditionary force of thousands of troops prepared to go to war anywhere on the planet. And, of course, nuclear weapons.

Each year, about half-a-million people are murdered worldwide. Naturally, these deaths have devastating effects on the victims’ families and loved ones. But there are also killings that reach far beyond friends and family and change the world. These transcendental murders can turn out to be very expensive. The iconic case is the 1914 assassination of the Austrian Archduke Franz Ferdinand in Sarajevo. His death set off a chain of events that led to the outbreak of World War I and the deaths of 40 million people.
