The thing about nuclear weapons is that no one seems to understand the whole irony about them. For starters, no one is even going to use them and therefore it seems absolutely stupid to squander money on something that is never going to be used. In these days of "low-tech" terrorism, there are plenty of other ways for nutters to kill people.
The elephant in the room is obviously the fact that each political party is trying to maximise it's "green credentials" and it seems ridiculous for a political party to say one moment that we should limited our carbon footprint and limit harmful omissions whilst saying on the other hand that we would be prepared to use nuclear weapons. I suppose at least Trump is consistent in wanting to have both options available with which to destroy the planet .
