In terms of radiation, everywhere within an 8km (max) radius will be irradiated. In terms of radiation that is pretty bad. Because radiation alters cells on a molecular level causing mutations. I am aware that the figures vary from each bomb but radiation is something that we dont want alot of on this planet from a biological standpoint. I am not totally against these weapons as of now unless they are used on a civilian population, or used too much. But i do believe that we would be much better off without them.

Maybe I should've added "over time" Yes you'll get irradiated if your within a few miles of a nuke, but unless you're dropping several nukes in close proximity that damage will heal. I mean, nuke or missile, either way your dead - not much difference there - and over time there really isn't much difference to the surrounding environment either.

The damage will heal yes but it is an unnecassary damage, that will take time to do so.

In the sense that all conflicts are unnecessary? yeah - prevention is the best and most effective weapon.

Alot of conflicts are unnecassary yes. For the ones that are necassary, such as tyrants trying to take over the world you have a point. However nukes do not prevent anything.

...They stopped japan, they stopped the USSR, they stopped the USA, they're pretty good at prevention.

Stopped...at what exactly?
