Soon seventy years that ended the great war. That was a blossoming spring. On the streets hugging strangers, radios queues: to hear good news. That spring our nation began with enthusiasm to restore the ruins of strain: the enemy was driven out, it's time to restore order in the house.

We don't like wars, because they are for their interests politicians, rich or fanatics. But the native is called the great war because it was the great folk feat. People fought not for political values, and for his house, the garden around it, for the family. Naturally, that won those who fought for human values. And those who came to enslave defeated.

Now we all enjoy the fruits of the struggle of our ancestors for our freedom from slavery. And the fruits of their labor, because the military and the post-war generation has restored the industry, rebuilt the cities and villages, where now we live. The greatness of the nation's feat is that it worked not for themselves. People sacrificed their lives for future generations, for us. We, of course, living in comfort, much more to complain about life than they are.

Why war can teach a person? First of all, to appreciate the peace and brotherly to unite for the sake of it. Appreciate the possibility to live together with their friends, instead of waiting for them for years, from the front. To love and to be loved, and not to receive notices of death" suitors. Calmly walk down the street, and not run quickly to the shelter. To buy in the store, fresh bread rolls and not bake bread from quinoa.

The veterans can tell us how terrible war, as the world a better place. But they are becoming less ... So let yourself be aware of this, so large and small war has gone down in history!
