Show me a country that has been deterred by Australian F-111s.


The one bad thing (or good thing, depending upon your point of view)
about deterrence is that it is virtually impossible to show a 100%
certain 'win' for it. On the other hand, it is also almost impossible
to show a situation in which deterrence may not have played a factor,
unless an attack actually took place. In other words, the natural
response to your question is the challenge "show me a nation that
carried out their aggressive plans against Australia in spite of the
F-111. Since I have not read of an invasion or other blatant attack
against Australia proper (as opposed to against Australians, outside
of the country), I would be hard pressed to point to a failure of
deterrence. And while I haven't been observing ALL that closely,
I'd expect to have noticed a large scale incident that would prove
that reply wrong...
