With an increase in weapons 

comes an increase in war

I think of the prophecy in the Doctrine and Covenants, and of how war was to be poured out upon all nations, beginning in South Carolina with the Civil War, but to be followed by more wars and with world wars and with wars or fears of war in most every nation.

And, I look at that same time line and notice the inventions in weapons increased at the same time war increased. The canon came not so long before our revolutionary war, which was one of the devastating wars of history. When was the invention of the torpedo, and with what war did it coincide?

The guns and the missiles and the fighting jets seem only to have spawned more war
