A familiar divide
It's familiar. It's as it's always been. It's almost reassuring.
Today the leaders of Britain and America stand shoulder to shoulder in the face of an economic threat. Hours later, the leaders of France and Germany will stand together too. Europe versus the Anglo-Saxons once again.
This divide matters because France and Germany blame Britain and America for the world's economic woes. They argue that the under-regulated brash excesses of New York and London caused all the problems. Their underlying message at this summit is: we told you so. We need to ensure that this doesn't happen again.
That is the fascinating thing about this summit. The leaders here understand the need to be seen to stand together but they're here too, as of course they should be, to fight their own countries' corner.
And remember, these four veterans of the old world are far from the only players at this summit.
What will really matter is what's heard from China, from India, from Saudi Arabia et al. It's going to be quite a two days.
