Your scenario, if it created a nuke winter, however might relieve all the complaints of the global warming bunch.
There is no doubt if Iraq, which had long range missles capable of hitting Israel, could have hit them with a Nuke. Saddam had intel on, and was buying repair gear for Nuclear weapons he aledgedly did not possess. Were he to fire at Israel they assuredly would retaliate. Pakistan and Iran would then return the favor, if not Russia as well. The scenerio by which a Nuclear war plays out should not be unfamiliar to anyone have in their life seen a television set. If nothing else the fact he could, and was motivated to, hit Israel makes claer the threat he posed to stability in the middle east, further Iraq is the perfect staging for the left side of a dual attack on Iran, which certainly must be being considered, given that we know if they don't have a nuke they are damn close to having the fuel, the missle, and the plans for a warhead.
