All right, Germany could not possibly have bombed Britain or Spain or France or Czechoslovakia in 1938 because of RAF air defence capability in 1938.
And, as usual, evasion noted. As has been repeatedly explained to you, and you have repeatedly ignored, senior Luftwaffe officers themselves stated that they couldn't have bombed Britain effectively in 1938; one stated that the most they could have achieved were "pin pricks." And no one said anything about France or Czechoslovakia.
As for Spain, the planes that bombed Guernica flew from Burgos, which is less than 100 miles away by air. But any bombers flying from Germany to London would have had to have flown, at a bare minimum, 350 miles each direction, and that's assuming they all flew from Emden, which is totally unrealistic; there simply weren't enough suitable airfields in that part of Germany. It also assumes they would have flown over the Netherlands, which would likely have resulted in a Dutch declaration of war.
In order to avoid neutral countries, most bombers would have had to have flown about 500 miles to reach London, from airbases in Lower Saxony and Bremen. Additionally, large raids burn more fuel per aircraft, as time for take-off, landing, and forming up must be allowed, on top of the inefficiency of flying in formation. So such Luftwaffe operations as could have been mounted would have had to have been fairly small, and carried reduced bomb loads. These attacks would have been suicidal in daylight, and at night they would have amounted to the aforementioned "pin pricks," assuming they could have even found their targets, which is questionable in 1938 and 1939.
As for the French, with their weak air defenses, and who were much closer to Germany, please explain why the Luftwaffe didn't merely bomb them into submission in 1939 or early 1940.
Additionally, you ignore the fact that the RAF had bombers, too. The Whitley was quite capable for the time, and over 100 were active in the fall of 1938. Further, the Wellington was just entering service, and so was the less capable but far from useless Hampden. Plus the numerous Blenheims could have staged through French bases to bomb many German cities. Finally, unlike the Luftwaffe, the RAF had prepared for and practiced night bombing.
