Lets Get Real:
This is NORTH KOREA reminding the US and the rest of the WORLD that it is still a problem, the ONLY reason the US has not taking action against North Korea is the simple FACT that is a nuclear armed power that even CHINA cannot control even if it wanted too. The NK Regime has seen that the Biden Administration has been diverted by the Crisis between the Ukraine and Russia and the on going talks in Vienna between the US and Iran. The ballistic missile test is a reminder to the Biden Oval that they are also a rogue nation and need Presidential attention, they cannot feed their own people and expect the US to help them out with no concessions on their part. On the whole the Biden Oval can put North Korea on the back burner, its most recent and urgent problem is the tensions on the Ukraine and Russian border. The North Koreans will never give up their nuclear arms, its the only thing they have that get the attention of the powers, one doubts they will ever go to WAR, at this would mean the end of the REGIME.
