It's all part of America's imperial designs and muscle flexing which has mainly been driven politically by a neocon agenda. Interestingly and fairly typical is the omission of information concerning North Korean casualities, as if their lives were of no consequence and thus not worth reporting on. Also quite interesting is the downplaying of of US casualties which is reality were almost double of that mentioned in the Sun's article.
