A weak and minor atomic bomb, like the one we dropped on Nagasaki is more powerful than all the conventional bomds dropped by the allied forces in WWII. The Hydrogen bombs of today are 1,000 times stronger than the one dropped on Nagasaki.
There is no such thing as a minor nuclear explosion
Of course there is. Ever hear of a small tactical nuke? The current testing, design and technology is focused on smaller nukes, not for large globe busting nukes. It's the wave of the future for nukes......
That's not true. There are all types, from dirty nukes to hydrogen bombs. Pakistan and North Korea don't have hydrogen bombs, do they?
There is such a thing as a micro nuke, much smaller than the Hiroshimi and Nagasaki weapons, but they are likely well beyond the capabilties of the N. Koreans and even the Chinese.
