Just because North Korea failed doesn't mean nga wa na jd clay au, they are still new to space exploration, as sir rodsky said in the previous comment space exploration has always a gamble, remember the 1986 launch by the US named Challenger Space Shuttle blew up in just seconds after launch killing all of the crew members. At least this try by north korea didn't have casualties, even if this launch is a cover up for future nuclear launches or not . Its still a big accomplishment on the part of North Korea, though their people may be dismayed because this was a tribute to the centennial birthday founder of north kor. This may also cause some tension between US and north korea because US will stop their food aid support because they went through with the launch..
