Is this a joke?
I find it very hard to believe that this guy actually worked with the Liberal Democrats because he sure doesn't understand them.
The party has no ideological objection to Nuclear Power but they believe there are much better alternatives (with there are). Above all, the UK simply cannot afford them right now. In fact I'll go further at no point during the next couple of terms can we afford to even THINK about Nuclear Power. Even the consultation will be too expensive.
As for trident. The party line is regarding the cost. My personal opinion however is that a country the size of the UK having nuclear deterrent is laughable, barely any countries in Europe do, even those more economically active don't. Lastly on this subject, if a country, any country used nuclear weapons against the UK do you seriously think the aggressor will last long? The UK wouldn't have to do anything, just sit back and watch.
Lastly, haven't you seen any of the end of the world films? It's America where the astroid will land it's them who will save us! Plus doesn't the Liberal Democrats have UK's authority on astroids?
