The USA, since WW II, has become a purely military nation, and it is totally dedicated to the idea of instilling an in-control attitude into its population, especially the young.

It has thus declared war on everything our Victorian ancestors thought of as weakeners of moral fiber, especially intoxicating substances (except alcohol, which we gave up on) and youthful exposure to the enticements of sexual pleasure.

Anything that promotes control, like gun violence, stimulating fantasies of righteous revenge and buoyantly justified personal war, is good.

The ultimate goal is to get Americans to kill people gladly when the time comes. This has replaced life, liberty and the pursuit of happiness (remember happiness?) as the number one goal of this society.
