Obama tasked the Pentagon and intelligence agencies with examining whether it would be possible to take out all of North Korea’s nuclear weapons and related facilities. Could they effectively target all of this? They would need to update the satellite, signals and human intelligence. So much was not known or certain. Pakistan, which had nuclear weapons since 1998, had miniaturized their nukes and put them in mines and artillery shells. Did North Korea have that capability? Current intelligence assessments could not answer definitively.
