a global threat. I feel like that's at least one point we can agree on.
No. It is threatening the US, if it is in fact a thread tho is very questionable. I am pretty sure your anti-nuclear-missile-defense systems can take care of some shotty NK missles.
Oh and if you are afraid of the outbreak of WW3. I told you that if you touch Korea even with conventional weapons, then this alone might lead to a WW3 scenario.
Some people n your government must really like the game fallout so that they desire to create such a world.
