We live in difficult times. We have a pandemic, a cost of living crisis, and climate change. There is another danger – nuclear war. The UN said a small mistake could lead to war. This is because tensions are high in Ukraine, Korea, and the Middle East. The UN said we are "lucky" to have avoided nuclear war.

The danger is at a very high level. The UN warned that: "Humanity is just one misunderstanding…away from nuclear [war]." It hoped the Nuclear Non-Proliferation Treaty would help the world. It said: "Eliminating nuclear weapons is the only guarantee that they will never be used." The risk of nuclear war is growing.
