how about sdi having like 10% than after each level of future tech it increases the odds by 10%
If it also increases chances of nuclear evasion by 15% too, sure, why not.

Well earlier Civ games had ICBM's which had unlimited range - that's overpowered!
No, there should not be a defense against nuclear weapons, because they (defense systems) do not exist. Several posts have hinted that modern nations have the capability to intercept nukes, when in fact any program the United States has implemented (or attempted to implement) has failed dramatically (they are much too easy to circumvent). Furthermore, the United States is the ONLY nation to currently be researching nuclear defense. Why, you ask? Because 1) Deterrence is the only known defense against nuclear missiles. You have nukes, I have nukes, we won't nuke each other. 2) Missile defense is not actually "defense", but rather "offense", because a reliable missile defense system would give a nation the capability of delivering a first strike, thus upsetting deterrence. 3) The programs are enormous wastes of money, requiring millions (if not billions) of dollars in research for a product that will ultimately always fail because it is too easy to circumvent using simpler, cheaper technology. All other nations recognize this and don't work towards it because they have deterrence. This is why the only time nuclear weapons have been used in the history of the world was Hiroshima and Nagasaki, because the US was the only country with them, so we could use them. After that, no dice.
Sorry for the context and stuff, but I think it's fairly important. I'm not necessarily saying that maybe the game wouldn't be better in fixing nukes, but if you want the game realistic then, well, there is no such thing as missile defense, or any kind of nuclear defense (and please, please, please, don't ever let anyone tell you there is). Perhaps the diplomatic section could be improved, as some have suggested.
Nuclear weapons in Civ 5 really ought to carry more repercussions than just being a simple 'I WIN' button. There should be increased detection/prevention (particularly with the A-bomb), major diplomatic penalties, long term side effects, and, perhaps, plummeting happiness with their presence/use.
Does the AI nuke you if you don't fire first? I was rolling up AI players that had been nuking other AI players that never nuked me not matter how many cities I took.
