I disagree. There is very much a threat of nuclear war... Perhaps not immediately including NATO countries or even the former warsaw pact, but the threat in certain areas remains there.
Not really. when you look at Political reality, Iran will never use a WMD on anyone. Perhaps Israel may use the Samson option, but that would require them being forced to a point of no return. Korea's missiles act as though they were pirated; They can barely reach japan. Neither India nor Pakistan want Nuclear war. India needs Pakistan as a boogeyman, and without Terrorist intervention Pakistan will not attack India.
