Russia has practiced delivering a retaliatory nuclear strike

[yuppa]

Hello, my friend. Of course, no one wants to use nuclear weapons. But the new Russian nuclear concept allows for their use in response to NATO using missiles against Russia by Ukraine. This already exists and is ready for use. This is reality. As soon as Ukraine launches missiles on Russian territory, there will be a nuclear response against the countries that produce these missiles. No one wants this. But if this happens, NATO countries must know about the response.
This is war, it happens....

So then the US can also do so since the russians were supplying weapons to our adversaries correct?
