BS, there is a certain amount of thought that Indonesia stepped back from a full blown war during Confrontation because they suspected we might have gone nuclear.
Remember this was only 19 years after first use.
A nuclear storage area had been built at Tengah.
The 8 Victors had been replaced by 4 Vulcans.
Four Vulcans were a wholly inadequate and probably ineffective conventional bombing force. Any logical opponent could only draw the conclusion that they were for nuclear operations.
It could be argued therefore that ownership of nuclear weapons detered a conventional attack.
Exactly and I wonder how many times the fact that a nation has nuclear weapons has affected the outcome, take the Falklands War, did our nuclear credentials prevent other South American countries supporting Argentina? Or in GW1 did Saddam change his plans, not that long before there were stories he had used chemical weapons in his war with Iran.
We simply do not know what conflicts have been prevented as a result of being a member of the nuclear club. So for that reason it is a good thing to have, as I said earlier it isn't that expensive.
To remove the nuclear deterrent is akin to fighting with one hand tied behind your back, terribly British and sporting don't you know, but not very good when the other chap has a baseball bat!
