Has World Cup feelgood factor melted as Paris burns?

It is the evening of September 9, and the Stade de France is a sea of sound and flashing lights as the Paris public greet their World Cup heroes, embarking on another campaign. The golden trophy is raised aloft once more. The crowd bathes in euphoria, as they did, one million and more of them, filling the Champs Elysees the day after their triumph in Moscow.

France is awash with pride, a nation at ease with itself. The President of the Republic surrounds himself with the players, handing out the gongs and modestly basking in reflected glory, as presidents always do.
