This idea is important as it would reduce the number of unemployed youths that hang around street corners and town centres terrorising law-abiding citizens and instill in these people a sence of national pride and discipline.
Todays youth generation need to have their attitudes changed and begiven something to believe in and to be proud of. A term in the Services could teach them a trade and give them the necessary skills and experience for securing employment after their service is concluded.
We might even be able to fill the skills gap and not have to rely on foreign workers to fill some skilled vacancies.
The prison population, with all of its associated costs, could be reduced significantly if those youths imprisoned for petty crime or reoffending were given National Service as an alternative. I can see this being a much better way to reform these characters than prison ever can.
