Example

When the nations of the Omaha Pact came upon the smoking ruins of Moscow they decided to make an example that would be remembered through the ages.  The glassy ruins of the Kremlin were left intact.  The forces of the Omaha Pact proceeded to demolish every whole structure or fragment of a structure within one hundred miles, not kilometers, miles of the Kremlin. Every brick was separated and smashed into small pieces, and every scrap of wood was burned to ashes. Every tree was cut down and uprooted and with every other form of plant life was also burned to ashes. When this task completed all the ground within one hundred miles of the ruins of the Kremlin was sown with salt. 
While tourist groups are now brought across the Death Zone to view the ruins of the Kremlin, which remains as a monument to the evils of the Russian State, any unauthorized person, usually an ethnic Russian, found within the Death Zone is summarily executed and is covered with salt, lest the remains decay and renew the soil where he fell.
