I think there is a difference between asking people (and not just young people) to go abroad to 'fight in foreign wars' and asking them to contribute to their country at home.
I wouldn't support the old-style national service, which enlisted young men into the forces and sent them to fight, but I am tentatively coming round to the idea of expecting everyone to 'do something' for the collective good. I haven't quite pinned down what the 'something' could be, but I think it could be very broad. I saw a (lovely) film called A Yak In The Classroom, set in Bhutan, where national service was tailored to the individual - in the story a young man was sent to teach in a primary school in a remote village. Not necessarily something that would work here, but there could be all sorts of options. In some cases the results might be remedial for the people doing the service, and in others it could benefit an increasingly divided society - in many cases it could probably do both at the same time.
Maybe everyone should have to 'do something' for a certain number of weeks a year and complete them within a five year period? The finer points would need to be decided by people cleverer than me, but something like that would allow for life events to be accommodated and for people to plan. Nobody need be forced to move away from home, but those who wanted to could be given a chance to live somewhere different for a while, and people could learn new skills, whether they are practical or 'people skills'. I don't know who would supervise any of this - that would be a potential obstacle - or what would happen if people refused to co-operate. Again, that would need to be decided. Maybe a reward system would work better than a punitive one, but something would have to ensure that those who could afford it couldn't buy their way out, as that puts the kibosh on many well-intentioned schemes. It has to be fair, but fairness can be very subjective.
As regards actual military action, I think that this should be addressed by a combination of prioritising diplomacy and ensuring that the armed forces are capable of a defensive response if we are attacked. A combination of Brexit (thought by some to have been engineered by Putin), an increasingly isolationist US, a powerful China (and India) and unrest in the Middle East has exposed our vulnerability in the face of a military attack, and much as I (like the vast majority of people, I'm sure) would much prefer to live in peace, freedom is never free - it often comes at a very high price.
What did you you think you would have by your current age that you don't?
