does sdi intercept nukes fired at a civ's units in neutral lands? I'm thinking of just putting 2-3 tactical nukes on 3 sides of my landmass, the sides that enemy fleets can approach from
if sdi can't intercept those nukes, then that's a very easy way to defend yourself (I've never been attacked from the sea in bts so far, but I saw the AI go for island barb cities with 10 destroyers and 5-6 transports full of units - if all it takes to defend yourself from that is 2-3 nukes, I am in!)
