North Korea test-fires another pair of ballistic missiles, South’s military says

While media paints the Ukraine situation as a WW3 possibility we quickly forget how North Korea is doing what they are doing. Bottomline, is there a justification for anyone suggesting military response if Russian military occupies Ukraine?
I would say only political consequences beginning with UN sanctioning if not expelling Russia.
North Korea like Iran will do what they are going to do and argue US and Europe have zero authority to dictate to a sovereign nation what military capacity one can have.
