Massive destruction weapons

For many years , wars have plagued the nations of our planet, either by political, territorial, religious, etc. Since many of these conflicts are very valid reasons for each side to fight them.

For the simple reason that no country would like to fight a war in vain, this leads to the creation of weapons of greater destructive power, such as weapons of mass destruction. Indeed, these weapons are harmful and why there is no control over its scope and sometimes you have to test and these damage the environment in a meaningful way. Using these means of destruction is something that really goes against human nature and against civilization that we reflected that although social progress mind we go back to humanely destroy human lives which are sometimes innocent.
