Ever since the earliest days of the Cold War (I'm old enough to remember the last decade or so of it clearly), it has been the stated position of the US that it will respond to the use of WMD's against US troops or territory will be met with the use of WMD's. Officially, the only ones that the US has are the nukes, and he wasn't quite crazy enough to test their mettle on that front.Shock and Awe said:In the Gulf War Iraq had substantial Chemical Weapon stockpiles and had the ability to attack Coalition troops with them. He didn't do this due to what substantially boiled down to MAD, except only for him as the US would still be there to end his ass. I'll admit I cannot recall a direct conflict with Nuclear Powers who had ICBMs, but the Gulf War provides an example of countries holding back their full power for reasons of keeping the conflict from escalating.thaluikhain said:Hey? Which countries do you mean?Shock and Awe said:Its possible, but Nuclear Weapons will complicate things. I do not think they will stop war completely as countries with WMDs have been attacked and defeated without using their weapons even when they had the chance.
During the Cold War (and to this day presumably) large scale exercises and simulations were constantly run - often known as "war games". They always came to the same conclusion, regardless of how much the opening steps were varied or scenarios varied. Any conflict that broke out, localised or regional, that brought two nuclear armed powers into combat with each other would always end with the worst case scenario: Strategic Nuclear Exchange.
These were born from the anxiety surrounding various "proxy wars" (Viet Nam being the most well known of the Cold War era probably) where the possibility of escalation, while remote, was always possible when two nuclear armed super powers have dick-waving competitions.
The fact that most nuclear armed powers have no real desire to winding up being reduced to glass themselves means that for the moment the likelihood of a war on that sort of scale seems fairly remote. Should the Iranians turn out to have some in the near future, all bets are off though...
