I would (gently) suggest that you look around GitHub for a project titled OPEN-RISOP. That is a simulation of ~2100 warheads targeted on the USA. This is the red team approximation. There are three scenarios represented: Counter-Force, Counter-Value, and a combination of CF+CV. Counter-Force being an attack aimed at strategic assets and the immediate supporting facilities. Counter-Value is roughly what is being wrought upon Ukraine now. The trade off CF+CV is a blend of the two. It is also interesting that some targets (of which there are 9,000+) do not have a fallout pattern associated with them. My presumption is that those targets are neither hardened nor have a wide land area. An example is a natural gas compressor station. They do not need a warhead, but could be sufficiently damaged by a conventional cruise missile warhead.

Russia does not have enough nuclear warheads to hit every US target With one, because some of those warheads are assigned to targets in the EU and in other countries. So the ~2100 is a fair guess. That Russia is rapidly burning thru cruise missiles, is good, because that also goes into equations involving targeting. Some of the 9,000+ targets in the hypothetical OPEN-RISOP list are thermal power plants, the same type that are currently being hit in Ukraine.

The sooner that Russia gets out of the global strategic warfare game, the better for all of us.
