The weapons of mass destruction

Should every country have the right to produce nuclear weapons? What is the main role of the UN in reducing or preventing others' activities? Everyone wonders about those questions. Even looking at the name of the term "weapons of mass destruction" leads us to feel nervous or afraid. Many countries' goal is to parade or show off their power so that other countries will fear for their security. Chemical weapons is considered as one of the nuclear weapons. In general, weapons only have negative impact on our life such as killing people and other living organism. Moreover, They unfortunately have long-term impact, most dangerous thing, on environment. Hiroshima in Japan and Chernoby in Russia are good examples of considerable chemical pollution or disaster. The U.S army exploited Iraq war to use its new and powerful weapons; consequently, Iraqis are against this war. However, there is a controversial question, why a developed countries can pursue or make the weapons of mass destruction. No country and even the UN demands them to halt their activities. Who is the victim and who is the guilty? Those two questions should be asked by public.
