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The 8 Victors had been replaced by 4 Vulcans.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.
