"North Korea has broken its silence with a colorful statement attributed to Kim Yo Jong, the younger sister to North Korean leader Kim Jong Un, that is perfectly timed to coincide with the Biden Administration’s first high-level visit to Asia.

At the same time, there are U.S. sources saying North Korea may be preparing for a banned weapons test.

With these moves, North Korea is seeking to influence policymaking in Seoul and Washington by reminding them of the threat Pyongyang poses. Kim has not directly provoked the Biden Administration — yet. For the time being, the activity at test sites might mainly just be for the benefit of satellites trained from above, a warning sent via satellite imagery. Kim Jong Un is waiting to see what President Biden’s Korea policy will entail - but is warning that his patience is limited."
