Remember, we signed an armistice, not a peace treaty. The same state of war that existed in 1953 exists today.
The public has been kept ignorant by a media that is in part ignorant themselves and in part negligent. Count yourself among a minority that recognizes there is no peace treaty ending the Korean War; officially that state of war continues.
Fighting merely was temporarily set aside, in the form of an armistice - an agreement to a lull in the fighting. That’s all it is; an official pause, not an official end agreed to by both sides. No peace treaty has ever been signed by the opposing sides in the Korean War.
North Korea has never kept its people blind to that fact. Compared to the U.S. and South Korea that is the one area the regime in the north has been more honest with its people.
