Putin met with the defense ministry leadership, representatives of the military-industrial complex and missile system developers, giving us more details on the Oreshnik missile that was used:
Especially noteworthy are the following two characteristics of the Oreshnik missile system:
Given the weapon’s designated tasks and range, it can hit targets across Europe, offering significant advantages over other types of long-range precision weapons. As you earlier noted, the mass use of this weapon would be comparable to the use of nuclear weapons.
In other words: As soon as Russia can and will build Oreshnik missiles on mass (which will likely be soon), the systems power and efficiency can be used in ways on ANY target within Europe that are comparable with the use of nuclear weapons. With three big differences: First; it doesn’t leave deadly nuclear radiation behind for ages, second; it can hit targets very precisely and quickly, and thirdly; it doesn‘t have to be nuclear. So, Russia basically told/showed us that they can and will use weapons that can deliver similar objectives/results as the deployment of nuclear weapons without needing to use nuclear weapons! So, in theory, they can use that system, get similar results as nuclear weapons would in Europe, while not risking nuclear war.
