Yes Pakistan was under sanctions. I think they were in sanctions since 1965. (Not too sure) Till 2001 if I am right. But Pakistanis have to confirm this or correct me.
Yes India was sanctioned from 1974 to 2001. It started with the first nuke test in 1974, although these sanctions were on technology etc., I think that was the same with Pakistan. But these sanctions had zero effect on India, because India was already socialist and had a closed economy with a huge public sector. Even China is under sanctions I think, especially for military tech.
Iran's sanctions are to completely cripple it and make it destitute. Its the most severe sanctions ever to be put on any country. They are even cut off from international trade, because now they are cut off from using SWIFT codes. Iran's sanctions are actually akin to war against a nation. It will stop when Iran dismantles its nuclear program (I suppose), but you can never be sure.
Yes they can. They are not a signatory to the NPT, much like Israel and India. Although uncle Sam will nag, they havent let that get to their heads. They have continually increased their nuclear arsenal over time.
on a serious note, why do the french and the british need nukes?
