Answer:
North Korea has officially declared war on the South.
Explanation:
When Ambassador Muccio says that there is an “all out offensive", he meant that North Korea has officially declared war on the South.
John J. Muccio was a U. S Ambassador to the Republic of Korea and coincidentally was the first ever. He was in the thick of the Korean war and when he said that there was an all out offensive, North Korea had just started hostilities with the South.
