I think he has a political suicide wish. He is actively trying to destroy his own party.
It’s a crap idea from an inept prime minister who has only had crap ideas. So far, after 18 months of leadership, it is his third idea after compulsory maths to 18 and banning cigarettes forever for those born after 2009. All show he is completely out of touch.
For further context, we already have cadets. In the last two years the MoD funded opportunities for naval cadets have been cancelled in their entirety. Given that there isn’t enough money to pay for training courses for kids who are already interested in a military career, I’m not sure where he thinks the money for national service will come from. And that just a practical issue with his uncosted idea, not a philosophical one about rights and responsibilities.
It’s not dissimilar from his Maths idea, in that they both show complete ignorance. Is he unaware that we have the highest level of school refusal in our history? If we can’t get 11 year olds into the classroom, how does he think we will get 18 year olds in? Maybe focus on getting 11-16 maths working first! The beauty of our sixth form system is that adolescents suddenly have choice and agency.
