Penrhos not Pyongyang.
Pyongyang has posters on the threat of imminent invasion by the USA, with slogans such as "our gun is merciless; US imperialists will never forget the lessons of history". Bangor's posters tend to alert the population to cut price offers on cornflakes at the Co-op.
Young people in Pyongyang have plenty to do: learning more about the wonderful work of the Dear Leader, weapons training and helping out on the land ensure that every minute is productive. I'm certainly not suggesting teenage girls on Maesgeirchen are taught the Korean military goosestep and how to strip an AK47, but wouldn't it be better if youth services weren't being axed and our teenagers had sporting and social alternatives to hanging around our town centres?
