Do nuclear weapons help to keep the peace?
Nuclear weapons proponents have often argued that the existence of nuclear weapons have prevented World War III. But these theories have never been able to prove a causation between the existence of nuclear weapons and the lack of a direct war between nations. In fact, the existence of nuclear weapons have done nothing to prevent the many terrible conflicts in the world since 1945, including most recently, the devastating civil war in Syria. What’s more, nuclear weapons are strategically useless to address the actual security threats facing nations in the 21st century, including climate change, terrorism and cyber-attacks.
