Question

4. Why do you think countries that formerly possessed nuclear weapons, such as Ukraine and South

Africa, may have given them up? Why do you think other countries, such as the United States, continue to
have nuclear weapons​

Answer 1

they decided to give them up because they realized that they weren't getting a lot of wars or raids and dont need them. the United states still has them because we are a big country with many threats and we have to be ready for anything.
