What if the US super volcano erupts and the US launches a nuclear war?

Children, don’t think of such things too simply. Thinking about things without knowing the importance and without logic makes no sense. It's not just the United States that's suffering from supervolcanic eruptions. It's the whole world. Just because volcanic ash covers the earth in the atmosphere for several times and hangs in the sky for several years will have an unknown impact on climate, temperature changes and agricultural growth around the world. May cause destruction. Waging a nuclear war is not as simple as you think. Just think about the era when the United States had atomic bombs, but the Soviet Union did not, China did not, and no other country in the world had them. Why did it not launch atomic bombs against any country except Japan (the purpose of bombing Japan was to end the war as soon as possible) After many years of war, the atomic bomb was dropped on Japan to avoid the loss of hundreds of thousands of people, and the war was immediately ended) It was in the era when China developed the atomic bomb but did not yet have the ability to project it - keep a bomb with you. But you don’t have the ability or the tools to throw it out. What use is this bomb to you? At that time, the United States did not launch a nuclear bomb attack on China. North Korea (which only has nuclear devices and cannot be said to be effective nuclear bombs), Iran, Cuba, and some other countries that are inconsistent with the United States still do not have nuclear bombs, nor effective delivery tools such as missiles or aircraft. Why has the United States not launched an attack on them? Nuclear attack? Even if he actually launches a nuclear attack on a country someday. What about the rest of the world? Why hasn't it done so after all these years?

China now has nuclear bombs, missiles, and aircraft. Will China attack any country with nuclear bombs everywhere? Who do you think the United States might launch a nuclear war against? Will Americans immigrate to a country in order to escape the disaster area of ??a super volcano, nuclear strike a country, and then occupy their territory? To live in that nuclear wasteland?
