How did the world react to Obama’s inauguration? In Istanbul and Costa Rica, at least, it was business as usual. But there were cheers in Berlin as Bush’s helicopter took off. Dubliners drank away their economic worries and toasted “O’Bama,” while the president’s former classmates and teachers gathered in Jakarta to wish “Barry” well. Londoners hailed Obama’s inaugural shout-out to non-believers, and a Ghana DJ celebrated a black man getting “into the black house.” And in Beijing, there were fireworks. Just not for Obama.
