americans claiming that the atomic bombs were necessary to defeat japan without an invasion. it's history revisionism at it's best, japan had already signaled willingness to surrender prior to the bombings but was ignored. the consensus among historians is pretty much that it was to field test those things and to intimidate the soviets, which were perceived as a growing threat.
also, slightly related: pretending like the germans would have won the war in europe without american assistance. no. just...no. (pacific is a different deal though)
Until the fire bombings there was no pleas for peace. Once they started the only willingness Japan had was a restoration of status quo antebellum so that they could rebuild and start another war in a few decades time.
The consensus? Take a look at Downfall by Richard B. Frank. http://www.amazon.com/Downfall-The-Imperial-Japanese-Empire/dp/067941424X
Until the nukes came along the Japanese believed that all they had to do was hold on and the Allies would give up. Should they not, then national suicide was preferred. The whole focus of the leadership was to kill as many of the enemy as possible and welcomed an invasion even if it meant the extinction of their people.
Even with the fire bombings, the allies were still suffering casualties.
With nuclear weapons the Allies were suddenly able to simplify things: One bomber, one bomb to wipe out a whole city. They could sit back and obliterate these Japanese at their leisure with minimum risk.
Suddenly that didn't seem so fun which is when the Emperor made his move (And also almost failed due to an attempted coup by the army).
from the top of my head (although there are numerous others) i firstly think of the strategic bomb survey of '46. if even the US military itself says in hindsight that it wasn't necessary it should get one thinking.
i know it's not how it's taught in american high school history, but on an academic level there is really not much of a discussion about it.
Wasn't necessary?
Strictly speaking no, however the blockade and bombardment would take years to grind them down, they certainly sped things up.
Also, I find it interesting that you're from the Philippines. While your country had be liberated, much of the Far East still remained under the control of the Japanese and every month the same number of people who died in those two bombings died under their occupation.
Nuking two cities to quickly end a war and spare East Asia more grief was well worth the price, imo.
