David Cameron and his team do get a bit frustrated by the Americans' lack of desire to get involved in the world. That means if you want to do anything, and you're the British Prime Minister, you've got to look for allies - where is he looking? I think increasingly the French.
We went into Libya with them, and I think he's principally got involved in Mali probably because he thinks he needs help with that alliance. It has its advantages in building alliances in Europe too.
But I think it's principally a question that if you want to get something done in the world, you've got to have an ally. Well, France is the only country in the world with a decent military - and that's principally why we're here.
