And the Stuka appears to have been constructed by someone under the impression that his opponent would not have an airforce. While an accurate dive bomber, and relatively sturdy, but it carried a relatively small load, and was neither maneuverable nor fast. Which meant that every time it encountered an enemy air force of even moderate coordination and capability, it tended to die quite a bit, as the British demonstrated in the Battle of Britain.
It's possible, that under blitzkrieg doctrine, then the thinking would be yes, the opponent would not have an airforce, or at least not one capable of resisting.
In the European land war, the Bf-109s, would sweep the skies clear of enemy fighters, in front of the Stukas, which would be attacking in support of the ground forces, nearer the front.
When used at the Battle of Britain, against radar stations and airfields, it was soon found that Bf-109s cannot defend Stuka dive bombers effectively once the Stukas commence their attack, and Hurricanes and Spitfires find that a Stuka with its dive brakes on, is practically a stationary target, thus very easy to hit.
As for attitudes to war, and exposure to things, I think it might be useful to compare perceptions of the war against Japan as experienced by British people (also the Korean War), compared with the war against Germany. VE Day was a big, big thing in Britain. VJ Day, not so much. The Korean war, is sometimes called the forgotten war, in terms of British perception. VE Day meant no more V2 rockets, no more blackouts, no more air raid sirens. VJ Day, in comparison, was more like "oh, it's over", for Britain, as it was that much further away.
The Houses of Parliament were damaged by aerial bombing, there are discontinuities in the stonework that remain visible today. For people living in Britain, then the experience would be that the RAF is defending Britain to the best of its ability, and it is very able indeed, but... Britain is still getting bombed. Defence only determines how badly you're being bombed, not whether you're bombed at all.
And in Germany, the Nuremberg Raid, was a significant defeat of Bomber Command by the Luftwaffe, but... Nuremberg was still heavily bombed, even though the RAF lost.
When the best defence only seems to minimise, rather than prevent, attacks, then that probably has a big effect on attitudes.
Also, did mainland USA have widespread rationing ? was there an air-raid blackout in place ?
