The North Korea has tested a 3rd Nuclear Device, much to the consternation of China, South Korea, Japan, Russia, the US and Members of the UN Security Council. Only a Crazy & Uncaring, Self Centred Leadership & its Military would do such a thing. We wait to see what serious sanctions would be brought against North Korea, & whether this country will continue to be belligerant & carry out more nuclear tests as approved by its leader young Kim & his Military Hawks.
South Korea, Japan & the US as declared North Korean potential targets will NO LONGER tolerate the blackmails & threats & actions (Remember sinking of the South Korean corvette, launching of long-range "test" ballistic missiles in waters off Japan; now long range missile threats to the US West Coast). This is no longer tolerated by peace loving and level-headed countries. Those who backed N. Korea inc. a long-standing Security Pact must now realise what a "mad" leadership could do. So, the present discourse of Nuclear Weapon to force surrender of Japan during WW II must be seen in the right perspective. The seriousness of extrapolation of this "A-Bombs" destructions of Nagasaki & Hiroshima benefits NO BODY except those who want to use "history" as an example to "teach" Japan a lesson or some other reasons. The Japanese will NEVER tolerate threats & will defend themselves to the hilt - they have been anticipating THREATS from Kim & his be"MAD"elled Military Generals, & ANYONE ELSE. May countries & their Leaders come to their senses, less INNOCENT people will suffer & our world be destroyed. God help us!!
We only fear nuclear weapons today *because* of Hiroshima and Nagasaki. We have MAD because we've *SEEN* what nuclear weapons can do.
You say you're not judging Truman, but immediately after say what he did was wrong. Kind of contradictory, don't you think?
Add to that, your very next statement is to force a judgement on a historical event in order to conform to a particular value system. That's what they call revisionism.
