Nuclear weapons are more likely to be used by terrorists or unstable dictatorships such as Iran and North Korea than the US, UK, India, Russia etc. The Soviets and US had a treaty during the 60's of not using nuclear weapons in a high altitude arena (Space or high atmosphere) to defend themselves for fear of it leading to catastrophic events that would affect the Earth globally, such as it being shifted off its axis. It's not in the interests of developed, stable nations to use them.
Ofcourse not, and that's why they should lead the way to get rid of them rather than ask these small and helpless nations to get rid of theirs while them, the big guys, gets to keep their own. Its these double standards that would make small broken countries look for Nuclear weapons as a savior for their grief and a source of pride and strength to their nation
It's funny how the verbiage used went from "attack" with the Western nations to "negotiate" for countries like Iran. Again, can't have it both ways so one can demonize the West.
Because these small countries look for negotiating with the west, that's the whole point, to negotiate from a stronger position. For example, Pakistan, a nuclear country that is always under pressure to either get rid of it's arsenal or keep Americans at their bases to make sure that such weapons of mass destruction don't end up in the hands of Taliban, Qaida or any other terrorist group. Yet at the same time when Pakistan asks for more aid from the U.S to fight terrorism they don't get half what they ask for, and that is even when they ask for money to develop an area such as Wazeeristan, the one with all the fights from Taliban-Pakistan in the last 2 years or so.
Another example is Iran, their project is all about justice, as they feel threatened by Israel that have a deadly combination of both Nuclear and Biological arsenal, and they're the only country in the middle east to have such a weaponry while Iran's pursuit for such weapons are blocked and handicapped which is justified, but why concentrate on the result and not the reason. If Israel wasn't in such a powerful condition military speaking, then I bet no country in the Middle East would even think of going towards such a pursuit. Keeping in mind that both Iraq and Libya had a history of suspicious Nuclear weapons ownage.
