So do three nukes. Which is why North Korea hasn't been invaded by Dubya - he's scared.
It might have more do with the damage that would be done to neighbors than being scared of three nukes. Clearly the North Koreans pose no threat to Americans directly. They do however poses a significant threat to US allies in the region and any action by the US, from sanctions to war, might cause the North to lash out at the South or Japan and as such they proceed cautiously - as they should.
Only a simplistic mind would conclude that 3 nukes scare the US militarily or economically to inaction.
