Why do they fear a US attack? The US have made absolutely no indications or anything about attacking NK. I think NK is using this as an excuse to build up their nuclear weapons. For what reason would US attack NK for anyway? President BUSH specifically told them US is not going to attack them. Seems like to me with NK's lame threats of claiming the world will suffer a horrifying nuclear disaster (as they say) is going far down the wrong road. Oh but the US are the bad guys...WHATEVER.
