not sure if someone else has suggested this (but I do know everyone has gripes with Nuclear Weapons)...
but how about Chemical and Biological Weapons!
Diplomacy could also have a new feature for treaties bannning some weapons, but of course some nations to secretly or overtly break those treaties and try to develop such weapons. Then you'll need spies/UN to keep a close watch on the WMDs (of course George Tenet... cough.. I mean the spies could be wrong about their suspicions....)
A biological weapon would be a nightmare, a plague across empires (mainly good for intercontinental fighting etc), chemical weapons would be more restrained in their targets. And nuclear weapons, don't talk to me about nuclear weapons - but my idea is to varying the types of nukes you can develop (neutron bomb, high yield, low yield, big bang, small band, etc)
All of this in my ideal CivIV would go hand in hand with the develop of the Terrorist.
