A nuclear weapon is a chip on the table, that is all it is. No country to date has fired a nuclear weapon on another nation (except for the one who embraces the war-on-terror funny enough). Sure a nuclear weapon is a threat, they are actually used to guarantee defence by using the threat of "don't mess with us, we have a nuke". It is meerly an excuse for a bargaining chip for a nation to get it's way.
It is a big chip on the table, and it seems like the US/Israel have both thrown their chips in, just staring at Iran. I don't think the US will ever use a nuke again, because then the other superpowers will turn them to ash.
