North Korea - 1 nuclear weapon?

It's believed that North Korea tested its Nuclear Weapons last week - which could turn them into a powerful country in the worldwide community. Looks like we'd better all jump inside our Fall Out shelters and say goodbye to the world we know doesn't it? Well first you have to look at the facts and guesses about other countries worldwide.

Recognised nuclear powers (who have signed Non-Proliferation Treaty):
Russia 8'232
USA have 7'068
China 402
France 348
UK 185
Iran (unsure)

Countries outside NPT suspected of weapons:
Israel +-200?
Pakistan +-40?
India +-35?
North Korea +-1?

And a bucket-full of other countries are capable of creating nuclear weapons using existing nuclear reactors (Canada, Mexico, Colombia, Peru, Brazil, Chile, Argentina, Norway, Sweden, Finland, Netherlands, Belgium, Germany, Poland, Ukraine, Switzerland, Austria, Slovakia, Hungary, Romania, Italy, Spain, Turkey, Algeria, Egypt, Dem. Rep. of Congo, South Africa, Bangladesh, South Korea, Japan, Vietnam, Indonesia, and Australia).

So we might not need to question the fact that North Korea has tested Nuclear weapons this month (according to US intelligence - i didn't know there was any) but when you look at the stats, is it hard to see that other countries world wide seem to pose a bigger threat?

If the US are behaving as they usually do, then they probably have all of their "battleships" sitting in some bay in South Korea, so if North Korea fire their Nuclear Weapon (singular) on the very important Alaska, then they won't exist for more than two seconds, before the other coutries in the world with nuclear weapons (USA, Russia, UK, France, Israel, China and India) respond. Iran is the only dangerous country, but only appears dangerous due to forceful American opinion.

So, in the wake of WW3, I shouldn't worry too much... the only real threat is George Bush.
