The US recently put the world on notice that everyone needs a larger military and should develop their own nukes if they can. I fail to see how that will continue to decrease violence.

There have been no large scale wars since the development of nuclear weapons. The data available thus far suggests that mutually assured destruction prevents total war.

I live in a county in which most people are armed. There are very few attempts at carjacking.
