Because Brexit isn’t risky enough, apparently, Britain’s Conservative government has decided to embark on another project fraught with potential for failure. For many years, the country has been arguing furiously about a big expansion of London’s Heathrow airport. Having once opposed the idea, the Tories say they are now in favor.

Prime Minister Theresa May is right: Heathrow needs another runway. But the government’s announcement settles nothing. Even now, no sensible person would bet on this expansion ever going ahead.
