The Sun: PROPAGANDA chiefs in North Korea have made a film which appears to show an invasion of the USA in revenge for the Korean war.The YouTube clip begins with historic footage of American and South Korean forces attacking the communist North during the 1950s conflict.It shows children crying and scenes of devastation while the Stars and Stripes flutters. Sombre instrumental music can be heard in the background before the mood of the video changes. And as the tempo of the soundtrack picks up modern footage communist soldiers can be seen preparing for war.Naval troops are shown boarding a boat and air forces get on helicopters and planes. The footage then switches to US President Barack Obama making an address at the White House moments before Korean troops are shown to land in a foreign country – supposedly America. Korean warplanes are shown to drop bombs on the foreign land and thousands of soldiers are seen parading the streets of Pyongyang. The three-minute long film also shows clips of the South Korean government meeting before bombs are fired towards Seoul.
