If national service is back I don,t think everyone will be picked.Like thailand not everyone is picked and like turkey or greece it is for 18 mths only.Some will do uni or college and then become junior officer.Will it hurt them I don,t know and it could make them a better citizen.If it was around when i was 18 maybe i would not like it but accept it and do it.I,am sure they will be something to reward them after the time for doing it who knows.Like vietnam they went but after the GI bill free college and medical when needed in later life.So i would wait and see if it happens, My amercian friend did it and chose the air force he did not fire gun and had time in asia doing supplies and deliver them.Otherwise he would have being a marine but he served his country and he enjoyed his time back then
