But I said I wouldn't waste resources on a bomber. Bomber does not refer directly to heavy bombers, it refers to anything that bombs. The He-111 was a bomber, no matter the range or payload.
If I was more specific and said "I wouldn't waste resources building heavy bombers." then that would be a viable answer. And the odds are Adler probably means that but still I said bombers, He-111 (and all the others) are bombers.
And I think this is a perfect moment to go; So there. Nah, nah, nah, nah.
