To America of missiles North Korea will not reach, and if before the war the us military will be out in the ocean then Kim will make no sense to bomb the territory of South Korea. The same applies to Japan. Kim has no chance in this war.
North Korea is making rapid progress with their missiles. The latest test was of particular interest to the defense analysis. Some say that North Korea already possess missiles which can reach mainland US.
I don't think it's real. If the Koreans had a chance to develop missiles which can reach America I'm sure the Americans would have been a blow for all objects which can produce such missiles and launchers of existing missiles. Agree it's stupid not to react to how your opponent is growing strongly.
