If I had a child or grandchild with any inkling of joining the military, I would do everything in my power to dissuade them.
One of the few things that will grab their attention is when the services have to keep lowering standards to meet their numbers. I fully expect to see legislation, in the near future, opening up the services to illegals in exchange for expedited citizenship. No vetting required, impossible to do background checks - what could go wrong?
