As far as I am conceded,world without nuclear weapons is a good way for as. Using nuclear weapons will damaged country a lot. At the same time,after use this technology country must rebuilt their homeland. Such as, factory, school and house. Then after they rebuilt their homeland. Economy damaged country a lot. We have to protect our society and our homeland. It is a good thing for people have then, but not good for use in the war.Having nuclear weapons it can make your country stronger, but not for use in the war. That was a reason from my opinion.
