Are you worried that North korea is stocking up Nuclear arsenal?

I think that this world is going wrong direction. Nuclear arsenal is not good in any country. I do not trust North Korea.

No, North Korea will not used it for war, if they strike any countries with one, China will not even side with them.

I am no more worried about a nuclear attack from N. Korea than I was about the Soviets starting a nuclear war on the US. My theory is that N. Korea will not attack as it is surrounded by military bases and nuclear missiles that could take out the whole country in a matter of hours. They, on the other hand, do not have enough missiles to take on the whole world. The same was true of the Soviet Union. They were totally surrounded by US and allied bases and could have been attacked from all sides with no chance of escape. The havoc they might have caused is minutia in comparison to what the free world was capable of. I really don't worry about a nuclear attack because it simply doesn't make sense...especially because the nations of the free world will not strike first. I don't think the David vs Goliath will work with nuclear bomb.
