Nuclear: Part 1 of 4

What are the purposes of nuclear weapons? Should we really have them, or can we somehow protect ourselves without them. What are the risk? What is the ultimate reality about any nuclear bomb.

Nuclear weapons are often built by countries as a defense to their intelligence reports. As to why the other country which first presented their bomb developed it is the question. Why do we as a world create such dangerous things just to scare people. Is the risk of underestimating worst than the risk of overestimating another country and send a missile at them or drop a bomb when they really were not planning on attacking us? Either way someone is going to be unhappy.

The first way, underestimating is without a doubt a bad thing to do. If a country under estimates another, by thinking that they either will not attack or create their own bombs. The problem is that we are then behind and become the wear country of the world and to some may pose a target to conquer. The risk in this situation is that by not having nuclear weapons we look weak and in away let our guard down so we are open for attack. The positive of this is that no other country can say that we are staging an attack against them or anybody else.

The other way, overestimating, and attacking someone who really was not planning to attack us will. The problem is that once we do attack, the other country is likely to see us as a threat and send their missiles such as nuclear WMD's if they have any. If they do not have any missiles then most likely they are going to build up some sort of system of defense. One case of this is the time when the Americans who at the time had very little or no nuclear WMD's  heard of Germany building up or already having weapons, which then caused America to build up their defense.

The reality of a nuclear bomb is that it will either kill everybody from the heat and pressure, or from the radiation trails which it leaves behind. So even if we do for have reason to use a nuclear bomb such as to clear an area for our own use it will mot likely be pointless because of the huge levels of radiation that would make the area in inhabitable. One example of how radioactive are never the same as they were before the area was radioactive was Chernobyl. In the case of Chernobyl it was not a bomb, but rather a nuclear reactor which exploded and today, 20 years later is sill a rather large problem.
