In his own words:
Are we really happy to say that we'd give up our independent nuclear deterrent when we don't know what is going to happen with Iran, we can't be certain of the future in China?
As Mehdi Hasan notes over at the NS:
China?? Does David Cameron really believe that the People's Republic of China is a threat to the United Kingdom? That the Chinese, in the midst of supplying our high-street stores with much of their clothing lines, have prepared military plans to either invade and occupy the British Isles or nuke us to smithereens from afar?
David Cameron for PM?
You’re having a laugh.
