I was watching Gordon Brown on telly last night about the Russian diplomat expulsions. He looks good when he's being tough. He's no good at the touchy feely stuff like Blair. But he can do the 'rock of Fife act' very well in a crisis.
I just wonder if there is perhaps an element of this crisis playing well for Brown underlying the government's actions. As Galtieri found, if you want to look good, create an enemy pronto.
