If America doesn't want to share nuclear info fine, we could easily come up with a European Option, based on a joint French/ British detterent and it would be cheaper.
The Americans can please themselves, we don't have to pander to there every whim, and we are the only country in Europe who even makes an effort with the Americans, and still they throw it in our face.
It's time in my opinion that the UK became less dependent on the Americans.
