One analyst said, presumably in jest, that the North Koreans may have "Hello Kitty" backpacks that they stole from Japan, but the only thing they are likely to hold is their lunch. He said:
We don’t take that seriously because they probably painted the radiation symbol over some Hello Kitty backpacks they stole from Japan,” the official said. “No one believes that North Korea has the technology to make a miniature nuclear bomb like that."Meanwhile, the North Korean soldiers have DARED others to try and take away their backpacks, and have assumed a fighting stance to demonstrate their ferocity.
