No this was an honest to goodness 1st strike by the AI, I'm playing the game just out of the box, the only thing I have done is edited hit points and rate of fire for artillery. I'm playing Regent. I checked the Military advisor a turn or two before India hit me and India had ONE tactical Nuke and that's it, they used that Nuke on my in Bangalore. As you can see by my Science Queue I was one turn away from Nuclear power. After India hit me then Persia declared war on India and hit them with some ICBM's, I didn't see this exchange of missles of course but if you look at the second screenshot, all of India's cities look like they took a nuclear strike, and Persia was the only other country with Nukes
