Very funny, and a good thing it worked out. Had the North Korean authorities arrested them, it would have been most unpleasant. They took a big risk.
Let them apologize staying in Australia if they want to. My suggestion would be never ever go back to North Korea please. Kim can do anything.
The two Australians should not be forced to to apologize on national television for dishonesty. Having declared that they are professional golfers was wrong, but they should have proved this and give them the appropriate punishment like suspension from the golf game. North Korea is wrong about this idea, it will not help.
I do not think that the Australians should have to apologize. The two Australian men played a prank and the North Koreans did not think that it was very funny. The Australians did not hurt anyone and they did not put anyone's life in jeopardy. The North Koreans should just move on and stop worrying about this prank.
The Austraiians should definately not do so. It would be very dangerous for them, and there is no gauruntee that they would be able to return. They should not have to apologize for saying that they are professionals golfers, whether or not they are, because North Korea is dangerous for people.
