Just something to keep in mind NFU's are just pledges. Russia, just out of the Soviet union had the pledge only to drop it.

If you look at the countries that have the pledge its none of the earlier adopters (Nato or former Soviet states). This is important because it signifies that the pledge is more of a political statement to provide comfort to existing nuclear states at the time the pledge was made. India similarly changed its pledge to only apply against nuclear states more recently.
