And therein lies the truth. It is wholly unconscionable that we would threaten a regional or non-nuclear power with nuclear weapons.
And is China a credible global nuclear threat? China's global economic domination makes nuclear war both unlikely, unnecessary and economically suicidal.*
Russia,OTOH, might benefit from nuclear blackmail, but would the threat be viable?
*China-US confrontation however is a different matter and should not be an element in British deterrent policy.
