Since the Arab oil embargoes of the 1960s and 70s, it's been conventional wisdom to talk about American dependence on oil from the Persian Gulf. But the global oil market has changed dramatically since then.
Today, the U.S. actually gets most of its imported oil from Canada and Latin America.

Two giant ships move through the Panama Canal's two parallel channels at the Miraflores locks, heading toward the Pacific Ocean.
The orange and white Bow Summer is a tanker. The deck of the Ever Dynamic is stacked high with burgundy and blue shipping containers. More boats like these are backed up in both the Pacific and the Atlantic waiting to enter the narrow waterway.

On a recent day, the ornate Palais de Glace museum in Argentina's capital, Buenos Aires, was packed with visitors browsing through a collection of photographs from the Falkland Islands war.
