The sh*t heading toward the fan? North Korea and nuke weps?

It should come as no surprise that North Korea is building nuclear weapons, and, it should come as no surprise that they'd probably like to use them on American targets and local neighbors (although the fallout would probably head north with the wind... I'm not sure they're ready for mass radiation poisoning.).. so I'll assume they're being made for American targets.

Im curious... were the PLCs made by Siemens?
