Is Russia closer to causing a massive War than North Korea or even the United States?

If oversimplification helps you sleep at night, then go for it.  But dropping the bomb on two cities still caused fewer civilian casualties than an all-out invasion, even without considering the inevitable "human wave" tactics they'd have been dragooned into, and the little fact that large portions of the country were on the verge of starving to death. 

Well if we are going to be Honest, the US could have ignited those bombs offshore as a warning to gage reactions first, then if they "had to", drop bombs on military targets, but the reason that is cited by some back then is that the US wanted to see what a Atom bomb could do to a city full of people, in retrospect it was the World's worst war crime in modern history, but no one has ever been charged or investigated  

I challenge you to provide solid evidence for your claim that a major motivating factor for dropping the bombs on cities instead of for target practice was just to see what they did to people.  The things were not exactly easy to produce.
