We have a problem with our nukes. They are old as crap. They need overhaul. And they need an overhaul and modernization that is going to be a few-hundred billion dollars at least. For example, our Minuteman III ICBMs are almost half-a-century old. They are intended to be used through at least 2030. Many of the nuclear warheads in the arsenal date back to the 1960s and 1970s. In addition to concerns over effectiveness, concerns over safety have been raised. This has people questioning what to do; some question it on ethical bases, some on economic ones, and some on practical ones. As we have seen, the functional need for nukes are less today than ever before as conventional bombs have gotten more advanced. Starting around the time of the second Iraq War, smart bombs got very smart. During WWII, you dropped a ton of bombs within a determined area and hoped a few hit the intended target. Today, a B2 Spirit can literally drop a guided bomb from over 10 miles high in the sky on dark and overcast day, and hit its target within about 10 feet. Therefore, you don't need to destroy a huge area to ensure you get your target. And so you don't need a nuke or the collateral damage to get the same thing done. In some instances, a nuke could not even do this. The accuracy of the Minuteman III ICBMs blow...you'd need a big warhead with a wide proximity of destruction to compensate for the lesser accuracy. All of the most powerful US nukes are long out of service. Most of the nukes we have now are significantly lower (and variable) 'yield'. As guided bomb accuracy increases, the need for powerful weapons will decrease. The next generation of bombs will take this a step further and be able to find a target in a single area within one floor on a multi-story building. At the same time, many argue that nukes are deterrents. Nuclear submarines are always at sea and always capable of firing an ICMB in literally seconds. That gives someone a good reason not to attack. And the Cold War period of Mutually Assured Destruction (MAD) clearly worked...you had two countries with enough bombs to blow up the world and the two closest planets, yet these bombs were never used because each side knew that the other would make it rain, plutonium style. Sooner or later, the same nukes can't keep being refurbished and so either new ones will have to be designed or old ones destroyed without replacements. So where do we go from here? --- A good article on the topic can be found here: http://articles.washingtonpost.com/...-stockpile-nuclear-weapons-nuclear-facilities Quite a few exist.
