There are many that believe that nuclear missiles are, after the building of the Strategic Missile Defense wonder, so expensive and so likely to be destroyed without any effect that they are essentially superfulous; however, this is not the case. The following is a guide for the correct implementation of a full scale attack on ANY resource, navy, powerful army, city or continent. The essential concept here is to recognize that the reason your nuclear capability is limited is because your missles are nearly always destroyed by the enemy's Strategic Defense System; therefore, it stands to reason that in order for your capability to be restored, the enemy must no longer possess his/her Defense shield. So, your primary objective will be to make this happen. The first step is to decide who you want to completely immerse in radioactive slop. The second step is to use your spies to locate the enemy city which has built the Strategic Missile Defense wonder. (Try the capital first, then the larger coastal cities, or the cities that have access to fresh water which allows them to build nuclear power plants.) Step three is to secure a Right of Passage Agreement with your targeted enemy. Step four is to advance your Modern Armor and Mech Infantry units so that they are immediatly within range of the located city. The fifth step is to use these armies to attack and burn the city containing the SMD wonder. Finally, you can now release an unholy nuclear strike at your discretion on this enemy with 100% success EVERY TIME. The opposing civ will never be able to reconstruct this wonder, so they will always be succeptable to a nuclear strike. There are three things that you can expect to require for this strategy to work: 1- You must have at least fifteen, but preferably twenty modern armor units for every civilization which you plan to use this strategy on. 2- You will need a large amount of gold, as locating the correct city for attack may be significantly expensive. 3- You need many nuclear weapons, either Tacticals or ICBMs, that are in range of your primary targets. This may seem expensive or excessive, but it is intended to be implemented by players that have researched the entire tech tree and are only in the 1300's. Often the game becomes sluggish after this occurs, as the weakest civs have already been destroyed, and those remaining are either a) stronger or across the ocean or b) have hundreds of mech infantry in their empire, making it extremely time consuming and expensive to take even a single city, let alone worrying about keeping it. The only sure way to ensure victory, and an enjoyable show of mushroom clouds and toxic lakes, is to intelligently use your nuclear missiles. You can expect other nation's civs to declare war on you after you release your unholy aresenal; these however are still protected by their respective SMD wonders, and can pose a significant threat if you are outnumbered; this can be especially bad if you are playing the two highest levels of difficulty. To circumvent a "you vs. the world" scenario, just use this strategy on every other civilization during the same turn. If implemented correctly, you will be the only civilization with any chance of withstanding a nuclear disaster. Keep in mind that when using this strategy, nuclear missiles become a main-stream weapon in your arsenal; if a fleet of Battleships/Carriers is harrasing your shores or sinking your ships, nuke them. If an army is preparing to cross your borders, or are in position to conquer a city, nuke them. If your enemy still has access to a resource that you don't want them to have ANYWHERE in their empire, nuke it. If you need to slow an enemy advance by destroying their road/rail improvements, nuke the land. The versatillity offered by a 100% effective nuclear weapon is boundless. One final piece of advice about using Nukes; if you decide to try and use this strategy on one civ, remember that if even a SINGLE unit is present in the radius of effect that the missile will still be succeptable to THAT NATION'S SDM WONDER. This can be very, very bad if you end up in the previously mentioned "you vs. the world" scenario, and many civs are passing through each others' territories.
