What a brainless twat you are
Okay, Mr. Thickie, let me explain how it is for you. Sadly, I don't think I can manage to simplify it to words of one syllable - but let's see how we get on.
Nuclear weapons. They're expensive. Really quite astronomically costly. For one nuke alone you could employ many hundreds of policemen, teachers or nurses. You could probably build a hospital or two. You could do useful things with the money. Or you could buy a nuke - which you'll never use (sometimes also known as pissing money up the wall). And here's the other problem with nukes. They're not only expensive to buy, but they cost a shedload to maintain and even more to dispose of at the end of their lives. Seriously. They make bailing out the banks look like small beer.
But, I can hear you snivel, they're a deterrent. They'll stop bad guys from attacking us. Umm. Really. September 11, 2001? Nukes had bugger all deterrent effect there. And here's the thing. Let's imagine that someone madder than you launches a pre-emptive strike. London has been destroyed. Birmingham is rubble. Liverpool is smoking. What are you going to do? Retaliate? Why? If you launch a counter strike then two things will happen:
1. You will fail to resurrect the dead in the UK.
2. You will be responsible for mass murder of civilians (because, make no mistake, 99.999% of the people that you kill will be innocent.)
If, after reading this, you decide that you probably would counter strike then I can only conclude that you're an evil fuck, and I hope that you meet a sticky end. If you decide that you might not attack - you'd just pretend to - the deterrent effect is broken.
As for nuclear power, I'll let you have it. Seriously. Build more nuclear power stations - but only once you've cleared up ALL the mess from the nuclear power stations that have been built already. And I mean really clear it up - not just sweep it under the carpet to be a problem for future generations.
