This is superb advice.A pleasure I assure you Now I ,Sergeant Heritic and many others have taken the time and trouble to give you assistance so please run with it and remove from your head any thought that you are a second Tom Clancy... you are not
As has been superbly pointed out ,the US armed forces have a duty to remove from Japan the ability and the will to wage war. PLEASE think about this... IOTL it was decided by the allies that unconditional surrender was the only option that was to be given to the axis powers. You should ask yourself why. after all European history is littered with enemies signing peace accords when it became obvious that there was a 'winner' So what is different in WW2 ..THINK
Now in this ammended pod which I gift to you, there is a possibility and a slight one at that, that there could be a political settelment before Japan is reduced to a tattered ruin . Remember that there is no benefit of foresight here, no super weapons [yet] no magic bullets only a lot of exhausted people doing their very best in a situation not of their liking and not of their choosing and turning themselves into heroes heroines in the process .Despite this your protagonists are all too human and are subject to a variety of pressures fom a variety of sources
Good luck and remember NO TOM CLANCY![]()
Think like an AMerican or ALlied COmmander in 1945, not like a citizen of any later era.
