What can we do to prevent wars? ответ на с переводом 5 -7 предложений

   To prewent war... Question people are asking for ages. It seems so easy just stop solve problems using agression! But how we can see it doesnt work. In my opinion people must become more wise and rational to stop all those horrors  which happen in the points of the war. However only time can help us with it.
   In spite of anything I think humanity slowly but correctly goes to their purpose -  peace all around the world.
