Then you fought against NATO's adversaries in the Cold War.
Anyhow... The USAAF wanted their bombing to be more precise so took greater risks bombing in the daytime. The RAF just preferred carpet bombing anything and everything at night.
And yet, the USAAF pretty much resorted to the same tactics during the day since the weather over Europe is nothing like the clear skies over the American southwest.
Until the delivery of a suitable long range fighter escort, daytime bombing raids deep into German territory were almost suicidal. However, how much greater the risks were is questionable. There's massive risk in forming up bomber streams in pitch blackness with no navigation lights. Also, as opposed to the daytime when some hawkeyed flight crew can spot enemy fighters at a good distance, night missions had to deal with night interceptors that could get within 150-100 yds of a bomber without being seen.
As for the RAF and carpet bombing, it was considered a viable tactic at the time. It went beyond merely looking to demoralize and dehouse the German workers and disrupt city services. It was also a tactic used to help deal with the dispersal of German manufacturing from large factories to several smaller facilities.
The simple fact is, whether USAAF or RAF, your life expectancy as part of a bomber crew wasn't very long.
Ah, go easy on 'em. For the RAF, managing to hit the continent of Europe was a major feat of skill.
As opposed to the Americans who needed someone to point out where Europe was on a map?
