The fewer countries with nuclear weapons the better IMHO.

In the old days, I sorta trust the USA and the USSR to talk to each other before launching a nuclear strike. These days, USA and Russia, same. They are sorta mature in this respect. I don't trust any other country. Especially non-Christian ones. Granted, USSR was non-Christian and anti-religion. Perhaps in this case anti-religion is sorta anti-non-Christian?

I preferred that Iran lost its capability without being bombed.
