So buy a shelter in case of something other than a thermal nuclear war? I would think the idea behind having a shelter would include nuclear war as a distinct possibility.
There would not only be a second wave, there would be third wave and more. Russia is not the only possibly hostile nuked up entity. Some of these entities actually know how to fight a war with reckless abandon and without mercy.
They have no false illusions about nation rebuilding.

Russia is the only country with the ability to hit the midwest, which is where these silos are located.

But if you knew anything about nuclear delivery systems, you would know that.
