25 years ago I might have agreed with you. However conscripting people for military training is not remotely similar to conscripting them to fight a war. It's not a bad thing to have lots of people (men) trained well enough to repel an invader at short notice. Historically, such things happen far too often. If they don't happen - well, no worries, a bunch of lads got to shoot at things, blow shit up, and play with big machines.
But yeah, I can see this particular situation just causing problems.
You can class anything you like as a mental disorder, and what is or is not a disorder is determined by weird old academics divining this week's zeitgeist. DSM-5, for example, is radically different to DSM-4. Why? Has the landscape of mental illness changed? Of course it bloody hasn't. But fashions have.
