Dude your claim to fame is growing plants sideways so please don't talk about nuclear technology.
You can't even be objective about politics, leave science alone.
The fallout and aftermath would be practically nothing, it would take thousands of bombs to make anything uninhabitable.
It's not the movies...
You display the arrogance of the terminally ignorant every day, it's no surprise that on this subject you're running true to form.
'the fallout and aftermath would be practically nothing'. If this is the case, why have residents of the districts near Fukushima been told they'll never get to go home? Why is the area around Chernobyl considered permanently uninhabitable? Congratulations, you've reached a new low; 'dangerously stupid'.
Because the DPRK is building weapons purely for their deterrent value, he's very likely to enhance their value in this regard by employing the use of extremely radioactive contaminants, specifically to poison large areas of land, including cities and other built up areas.
It's in fact a trivial technical problem to build conventional explosive fired dirty bombs that can contaminate city sized areas and unlucky districts downwind.
Kim has made it clear that an attack upon him will trigger precisely such retribution, and there is a certain precedent; Saddam ordered every oil well in his country to be set ablaze to deny them to his enemies.
The scariest fact of nuclear technology is that such materials are very easy to come by and are in fact difficult and expensive to contain so they don't cause widespread damage.
I realize that your ignorance is incurable and your stupidity impenetrable, Stinkydigit.
I'm including these facts for others who will read this. Everyone else needs to know the truth.
