Люди, , . хочу поразить учительницу, мол, не все заранее, вам больше) you have received a letter from your english-speaking pen-friend john who writes so you see that i enjoy a history of war. do you like reading history? why? in my opinion history explains things to us and warns us about the future. do you think it is important to know what happened in the past? do you think people will ever be able to live without wars? what should be done for it?

Hello John! I enjoy different types of books. But the one that I like the most is about history of war. I love reading it too because it brings up a lot of interesting and very useful information. In my opinion it's important to learn and know history, so you will know what will happened in one or another situation that was long ago in a dark past. Also you wont do the same mistakes that were done back them. I don't think that people will ever be able to live without wars, because there are always two or three people who want more power. I don't have an idea how to make a peaceful life forever or even for once.

Hi John! 
I am glad that you dont forget to write to me!
I believe that it is important to know the history, because it constantly repeats. I agree with the words of the great philosopher Cicero, that "History - witness of the past, the light of truth, living memory, the teacher of life, the messenger of antiquity."  But the story is also cyclic. Unfortunately, the rulers and the authority comes on the same rake. War leads to the ruins, tragedies, casualties, deaths and tears ... But not to win. Sad is the fact that during the war a lot of people are very terrified. People do not know what to do and whom to listen to. They sell their votes. They are quiet. The main thing for people - it's not afraid. Because the nation - this is important. Any war ends. But the history - never. Therefore it is important to know the history and draw conclusions, I suppose. 
That's my opinion.
Sincerely, (свое имя на английском)
