There are two opinions about building up weapons. Some politicians think that there •re too many weapons on our planet. They say the nuclear weapons that different countries have are enough to destroy all life on Earth ten times over. The progress in science and tech­nology makes people invent even more destructive types of weapons and this vicious circle has to be broken.
Others contradict them and say that powerful modern weapons guarantee peace and sta­bility in the world as they cool off aggressive countries and groups of people and make them think twice before starting a military conflict. Which of these points of view would you sup­port? Give your arguments!!!!
