Obama in Berlin

It may not have been at the Brandenburg Gate. But the genuine Obamamania among Berliners means that the keynote moment of the Obama European tour will have generated the right Kennedyesque images back home.

Perhaps, in such an atmosphere, the speech itself was always likely to be something of an anti-climax.

Diplomatic and campaigning conventions (and political prudence) meant that the critique of the Bush Presidency was rather a muted one, though commitments to oppose and end the war in Iraq (in the right way) won some of the largest cheers. So the candidate was never going to do what the Berlin crowd wanted, and lead them in a chorus of 'yes, we can' (though they did their best without him).

But if it was largely a speech of platitudes, they were always the right platitudes.

Being against torture, in favour of working with allies, aware of global interdependence, concerned about global warming, and committed to a fair peace for Israelis and Palestinians should hardly be earth shattering statements.

But, after the Bush era, they are statements which are needed, and which are even capable of generating great enthusiasm.

That may be more important than Obama's rock star status in explaining why a speech aimed at Americans can play so well with a European audience.

The challenge to Europeans, over Afghanistan in particular, might have been stronger than it was, not least to help allay fears that Obama's popularity abroad was a sign of weakness in international affairs. But the US mood has changed since 2004, and there are less takers for isolation as a badge of pride.

One of the ironies of Bush's polarising Presidency is that it has made it relatively easy for Obama to give a speech which has narrowed the Atlantic.
