I have mixed opinions on the issue of small countries and nuclear weapons. My own country has an estimated 30% of the world's known uranium reserves and we are a technologically advanced nation so clearly we are well capable of becoming a nuclear-armed state.
As early as 1956 the Australian government investigated obtaining tactical nuclear weapons from the UK. We also poured a lot of money and resources into the
Blue Streak missile program with the obvious intention of arming them with nuclear warheads.
Of course, that never came to pass. Apparently the British government back then was warm to the idea of assisting Australia in that area but the US definitely was not. Kind of sad really, especially since we let the Brits detonate a bunch of nukes out in the South Australian desert and on the Monte Bello Islands.
Then in 1970 we signed the Nuclear Non-Proliferation Treaty and ratified it in 1973, and that was that. Lucky for us we have powerful friends
