Well... if NKorea attacks SKorea, it would be a rockus.... i dont think USA would dare to invade/bomb, since china is so darn close. And since USA is a bit of interest to china, they would declare war. Then, Russia would attack anything nearby, japan attacks china, we here in sweden will just stand and watch like we always do. And oh yeah canada dies.
Not really, but its not that simple. USA cant just attack Nkorea without consequenses, and yeah. Nkorea got nukes. They made some testing in 2003 and 2005 that was measured too, so yeah, they got'em. And then, Nkorea have no communication with the surrounding world, wich makes USA go "Wtf is happening". Srsly, they are like that. I hope they wont attack... i would be really bad...
from an unsecure source i found out that Nkorea might have up to 8 nukes. Image them launching to important cities and places in USA. Say, Pentagon, DC (i dont know where USA has their army but yeah, you get my point), USA would be almost completely wiped out, no army, noone to orginize an counterattack.
I might be wrong, so please correct me if i am.
