Personally, I have no interest in "criticizing" foreign leaders for desiring nukes. I'd probably want them too if I was the leader of a country without them. However, we still have to oppose proliferation of nukes, and my concern about the argument you're making, which I've heard many times before, is it can be construed as favoring nuclear proliferation.
I remember the days when liberals opposed nuclear proliferation and were very critical of the idea of mutually assured destruction. Nowadays, we're more apt to hear about how understandable it is for other countries to want nukes because [United States, Israel, etc.]. Frankly, I don't care about who is being "criticized." I'm really not sensitive to the feelings of foreign leaders who want nukes. I'm more interested in my daughter not growing up in a nuclear wasteland, if she grows up at all. The more and more countries that have nukes, the more likely this is the world that future generations will face. This kind of talk is troublesome because it sounds a lot like we're making excuses for other countries to have nuclear weapons. This is an example of political ideology trumping sanity.
