Re: the survivors usually have not much will to fight more and get more bombs.
Oh I dunno.
My relatives tell me the flattening of bits of London and almost all of Coventry did nothing to quell the desire to get stuck in and do unto others. From all accounts Dresden was a *boost* to the German civilian morale, and Tokyo was firebombed "scientifically" using data gathered during and after Dresden, yet Japan was still highly bellicose afterward.
It all depends how the leadership depicts the way forward.
