If by study you mean have a basic knowledge of it, then I agree. I wish to see more people studying arts and sciences and less people studying war and politics.

IF a basic knowledge takes care of the need, that is good

IF you can trust the men best suited to be defenders, then that is good.

Those are judgements you must make for yourself.

I understand your reservations, and I am sorry that you have had those painful experiences.

Thank you for sharing them and your view.
