Satellite imagery shows NKorean preparations to launch a new class of submarine-launched ballistic missile.
A year or so ago, imagery showed a NKorean submarine with missile tubes. Now, imagery shows a test barge being prepared for loading with a missile. This test barge is of the type used to test ballistic missiles launched from submarines.
Maybe Trump could write a beautiful letter to Kim to stop this major development in NKorean capability to strike the US and our Asian allies.
