No. I would conclude that through my admitted policies and past performances owning nukes would make me less "safe". Because of their (often illogical) obstinancy, most everyone has been content to pretty well ignore Iran out of frustration. Going nuclear actually makes them a real threat, drawing a lot more negative attention.
India and Paksitan have nukes because of India and Pakistan. I'm not aware of any "attack Iran" agendas out of either country.
Israel has them (if they do...) because if you ask an Israeli to point out the enemy, he points and describes a circle.
But, you are asking me were I President of Iran.
I'm a firm believer that Iran does not have nuclear ambitions geared towards deterrence. They have an overvalued sense of self importance in the world, think they should be THE leader of the region and are very likely to adopt very aggressive foreign policies once they have possession. They have already made great strides on delivery systems.
