A key reason for today's skyrocketing oil prices is the behavior of one of America's closest allies: Saudi Arabia. The world's largest oil exporter was the driving force behind the deal that turned off the spigots. Riyadh is risking a crisis with Washington because the once-flush kingdom has gone broke sustaining a vast welfare state for an exploding population. America must push the Saudis toward privatization and fiscal reform. The House of Saud must get its house in order.
