Then you believe the Japanese war could not have been stopped by US forces over time.
Your original statement said, "The use of force is one of a final means to carry out one's will once all other means have been exhaustivly and futively tried." Military historians believed the Japanese war could have been won by US forces, but over time, and yes, many, many lives lost--but yet they would be mainly military forces and NOT innocent civilians. The ending of the Japanese war was quickened by the use of Hiroshima and then Nagasaki. Many claim it was to save lives. A tradeoff for Hiroshima...how many military lives would have been lost versus innocent civilians lives lost. This means the United States did NOT "exhaustivly and futively" try to end the war militarily.
Hiroshima AND Nagasaki both would be in your prayers.
Read a book. It could have, but after much more ground fighting and to most estimates, another year of fighting.
