The fact of Russia wanting to question the nuclear deterrent of the UK is a long running argument that is calm but can lead to acrimony sometimes. It depends on who’s involved because Russia worries and some of our representatives are not good at talking to other people.
The existence of a nuclear deterrent is unquestionable because of the provision of advantages that it gives and other states know about this because they can look at it. This brings up and out the questions over use and not over existence.
The Russia ambassador is entitled to ask questions about the UK and in fact authorities here welcome it because it gives a chance to respond fairly and in good time. However, it doesn’t lead to more than talking about the technology itself because Russia knows a lot about it.
The inherent fact about nuclear technology in the context of a deterrent is that it’s safe. It seeks to protect itself and this is the main reason for a rising threat or for an outward confrontation. This is how it acts as a deterrent – as experts often have to state here in the UK.
