You are totally right. I had the opportunity to witness at close range at an international convention North Koreans presenting papers. For each paper there was a pre-amble praising their Great Leader and it was always the same citation. At the first, every member of the floor was already smiling or giggling. But the same was reported in the second paper so much so the Chairman had to request for a stop to it. When I spoke to them during the interval, it came across to me that they really believed that they had a great country. They would not have the money to buy any souvenir back with them from the meeting but I would imagine that they would blame the government there (in that occasion, it was the US) of making the things so expensive. Such was the degree of indoctrination that these people had been subjected to.
