Devil here again, what is a civilised nation? This again veers to racism and xenophobia.
Would it be OK for Canada, Australia, New Zealand etc. to develop nuclear technology for energy and defence?
Where do you draw the line?
Canada and Australia have nuclear power. Canada's one of the biggest uranium exporters too. But no nuclear weapons. I'm sure it's not beyond Canada or Australia to develop them, but to what end? Who are the Aussies going to nuke?
