The modern arms race continues to present a problem in many parts of the world. What do you think countries should do to reduce this risk? How can the arms race be reduced or stopped (or is this even possible)? Should countries be allowed to sell weapons and the materials to make nuclear or biological weapons to other countries? Why or why not?

I think to reduce the arms race, countries should stop worrying about what other countries are doing, and focus on the bigger problems going on within themselves. The arms race can be reduced or stopped by a treaty that both countries would have to agree on stopping and they would sign it. Countries should not be allowed to sell weapons and materials to make nuclear or biological weapons to other countries, because it is provoking the opposing country. Another nuclear war would have so many negative effects on people, animals, food and water supplies, businesses, and the Earth, and I think it would be very irresponsible to destroy our world just for a war.
