Cutting France's Nuclear Arsenal?

The French possess the world's third largest nuclear arsenal. Is it time for them to reduce this following the precedent set by Russia and the US. As a NATO member state does it need such large numbers of weapons/ or nuclear weapons at all to defend it's national sovereignty. Seeing as the cold war finished 20 years ago, I can't see where the threat is supposed to be coming from. The very tiny possibility of an islamist terrorist with a crude radioactive bomb in a suitcase doesn't really justify it.
