Crimea, which made its debut in most Americans’ consciousness by way of being recently invaded by Russia, is an extremely picturesque tourist destination. While news media is inundated by images of Russian military forces occupying the Ukrainian peninsula, the businesses that depend on Crimea’s normally-robust $5 billion tourism industry are wringing their hands.

Remember the Sochi Olympics? Yeah. Me, neither. There’s been so much focus on Ukraine, we almost forget that just a short time ago we were talking about the “twizzles” of ice dancing.

Wearing a gray T-shirt, sunglasses and a ring in the shape of a human skull, Alan Fragoso, 27, takes a sip of his caipirinha. Fragoso used to be a sort of Brazilian Don Draper, an advertising man selling products to the nation's emerging consumer class. Then one day he quit. "What I really want is to work with projects I believe in," he says, "not to invest in consumption."

For a city, there’s nothing quite like the glory of winning an Olympic bid. The highly competitive process starts nine years before the games and involves untold amounts of campaigning and planning. Once selected, fortunate cities have seven years to prepare, updating their infrastructure and building new, impressive facilities. If they pull it off, they get two weeks to show it all off to the entire world.

On a warm summer morning earlier this month, dozens of building workers were putting the finishing touches to the restoration of Casa Moreyra, a 17th-century colonial manor house in San Isidro, the business district of Lima, Peru’s capital.
