Problem with the idea of the hotline to Moscow is that in civ3 the nukes will already be in the air. Your only real job will be to figure out your response (and don't tell me there won't be one, heh, heh). I posted in another thread about having a small wonder (I called it DEWS, Distant Early Warning System), that would give you the ability to detect nuclear launches. Maybe the best way to implement this is for each launch, your NORAD advisor informs you that a nuke is headed towards the city (or silo) and asks if you wish to launch. If you do, you pick the target to fire upon (must be the launching civ), and the ICBM blasts off. Civs without DEWS cannot see launches, and even if they have nukes you may fire upon them with impunity, no retaliation is possible until it is their turn. In fact, a small, dirt poor nation with a primitive military may even have trouble finding out it was you until a couple of turns later when the news leaks through the worlds diplomatic corps.
RE nuclear subs, I agree that on huge maps the range of tac nukes may need to be increased a bit, though this is really a matter of scale. I would not give each sub the ability to carry 8-10 nukes though. This lets the player skimp on subs, and IRL there is plenty that goes into maintaining an SLBM fleet. I would say 2 missiles per sub. Build plenty of subs, 20 subs each with 2 bombs will put a major hurting on the enemy.
