You and your AR-15 might be called up in an emergency as the militia, since our purported leaders have let our military strength decline so much. Bring your own ammo. (I know you have lots and lots of it in the basement, in quantities guaranteed to make a liberal quiver in fear and outrage.)
I favor a smaller standing military, with massive reserves and National Guard, possibly universal military service. I do not favor weakness, in any scenario. Weakness invites warfare.
