Someone tore up the script. Here’s how it was meant to go. Barack Obama was supposed to sweep into Europe on his first major trip abroad as the new JFK, greeted by adoring fans moistly waving little American flags. His progress would be part celebrity world tour, part celebration of the end of the Bush era. A needy Gordon Brown would bask in the Obama glow, hoping its rays would improve his own deathly pallor. Meanwhile, the rest of Europe’s leaders would fall to their knees, humbly agreeing to any request made by the visiting emperor, mindful that in a choice between them and Obama, their own electorates would choose Obama every time.
