No war, no ... Let’s better work, think, seek. The only real glory is the glory of labor. War is the lot of barbarians.

War is an event contrary to the human mind. How much pain, anguish, bitterness and loneliness she carries in herself ... Nothing in this world passes without a trace ... Even after many years, the war paints terrible pictures in people's memory: hunger, devastation, death, loss. All these terrible memories leave huge scars on the hearts of millions of people on our planet.

What is the meaning of war? What are people fighting to this day?

For several generations of the inhabitants of the Earth these questions have been of concern. Everyone sees the war in their own way: for some it’s a way of making money, the ability to tear off a “tidbit”, and for someone it’s the only way to protect themselves from the enemy and ensure a peaceful existence.

For us, war is the worst thing that can happen in the world. After all, it begins only through the fault of man. Why do people go with weapons at each other? Why are they killing? For what? Because of power, territory or material values? However, this is not even important. There is nothing more precious in the world than life. Life is the greatest gift God has given us, and we have no right to independently dispose of it. And this is exactly what happens in war. Murders, bloodshed, cruelty ... People forget about their humanity and turn into soulless savages, hungry for blood. This is wrong ... People have no reason to fight with each other. We all live on the same planet, we are connected by a centuries-old history. Of course, we are all different, and no one is perfect, but this is not a reason to wave weapons and kill. You can always agree and achieve peace without guns, missiles and tanks, but with the help of dialogue. We must learn to live peacefully and help each other
