AI Reaction to Nuclear Weapons

This may be a bit preemptive to assume, but in my one game of BNW I have noticed that the AI reacts more noticeably to the development of nuclear weapons. Within one turn of my construction of nuclear missiles, my two allies (Portugal and Morocco) shifted from a friendly modifier to afraid. Worth noting is that both were quite a bit behind me in tech. Has anyone else noticed anything similar?

Maybe nukes now increase your military numbers a lot more than they used to? Or else maybe because they see it as extremely powerful.

Well, think US and USSR. Both used to be allies, but as soon as there were nukes involved, both were afraid of each other. Allies or not, the AI doesn't WANT to be nuked.

Prepare for the cold war. Stock up those nukes until one of you gets embargoed and collapse anyways.
