I only wish we were as focused on keeping nukes out of the hands of the Pakistanis (in the late 90s) as we currently are in keeping nukes away from the Iranians.
The terrorists hadn't really kicked in yet, so the scare level to the rest of the world was less. The development of nukes in India and Pakistan were to offset each other, power-wise. They got them because of the emnity between their two nations, not as a threat against other nations of the world. So, they are peceived as less of a threat, more of a localized threat between two countries. Whereas, the Iranians would use their nuclear power against anyone or everyone, depending on whim. In particular, against Israel. All of western Europe would be under threat from Iran. This is what makes them so dangerous. Pakistan is more like a nagging nuke toothache, whereas Iran is a festering sore, with pus already starting to ooze out. Much more danger from infection.
