As fiery riots continue to torch the declining reputation of Los Angeles, the city’s mayor is reminding residents that the world’s eyes will soon be on them all. The FIFA World Cup, considered the largest and most-watched sporting event in the world, will be hosted — partially — by the city in 2026. For the first time that year, the soccer championship is to be hosted jointly in Canada, Mexico, and the United States in a giant North American kumbaya.
