People forget about the arms race that lead to World War I. They forget about the Cold War. Now North Korea, Russia, China, and Iran are all increasing their nuclear programs. Why? Because we did it first. When one country has a nuclear Arsenal built up, the other countries worry for their own safety and develop their own nuclear weaponry. We've all seen this play out in front of our eyes. It's the same with guns. When one person had a gun, it makes their peers feel like they need a gun to protect themselves. Are we going to arm every citizen of this country? We'll surely shoot each other from pure antsiness.
