Nuclear environmental damage option

[Asomeone 3]

If not there already, you could maybe add an option to enable nuclear environmental damage. This means every nuke detonated could damage the global environment, resulting in economic and social decline due to atmospheric damage. And the provinces around the nuclear explosion would have a dust cloud or something to show the effect of radiation.

On a mass scale, such as nuclear war, this could potentially destroy the world due to many nukes going off and nuclear winter.

I feel this would add suspense to scenarios, and would make both the player and the AI scared to use nukes, and might use it as a last resort. Maybe also nuclear treaties would help limit it a bit. I do feel like this is too much to add considering the game is releasing soon for all platforms. (Idk about IOS though, maybe of Lukaz sees this he could say if he wants) 

If this is too much, maybe add a cool effect in the modern world, where once it hits the late 1950s and onwards, whenever you nuke a country, you see a missile flying from random provinces in your country towards the selected target.

I think one way to simulate the environmental effects of a single nuke is by adding a special disease called radiation sickness that automatically spawns in a province after it gets nuked. This disease would be (nearly) unable to spread to other provinces but cause a lot of death and unrest in the affected province.
