As is so well depicted here, the Pacific theatre could clearly be just as terrifying and intense as the European one: whilst Nazi racial policy in Europe was as extreme as such things can be, particularly on the Ostfront, it was being carried out predominantly against civilians, and with particular virulence in the East.
Obviously there was plenty of horrific brutality, even in the Western European combat theatre as well, but there was also a certain degree of fellow-feeling between some of the ordinary soldiery. I'm making these comments in relation to how both sides of this coin are portrayed in Band of Brothers.
The Japanese fought rabidly, and were infamously brutal to their foes, frequently manifesting the same type of ferocious brutality that made the rape of Nanking so infamous. These traits were pretty common, it seems, amongst all levels of their soldiery, all over this theatre of combat.
* I'll be posting my short reviews of both books here ASAP).
