Guest G,

I think you're introducing a different subject here. Yes, 9/11 was awful, but it wasn't on 'our' soil, it was on yours. Of course, it has implications for all of us which we are all still living with but Hiroshima and Nagasaki had different implications for the entire world.

Even nowadays, there is less chance of terrorists using nuclear weapons than there is of national governments using them and if governments don't get serious about disarmament and preventing proliferation there is a continuing danger of the bomb being used again.

This is not to minimise the implications of other forms of terrorism, but the nuclear question doesn't go away just because other questions come up.
