I want to know the answer to the following question:
During what war was uranium-235 first used to create nuclear weapons?
All the background I'm provided with is that "Later, a much more complicated and far more powerful type of fission/fusion bomb (thermonuclear weapon) was built, that uses a plutonium-based device to cause a mixture of tritium and deuterium to undergo nuclear fusion.". Is that enough to answer the question?
Answer: no
