Was there a moment in WWII where it was truly on edge whether or not the Axis Powers would conquer Europe? I feel with American and Soviet involvement it was really only a question of how much of Europe would be leveled before they were defeated.

This has been answered a couple of times.

I found a great answer by u/DeSoulis that answered the same question two times.

Another, specifically for the Battle of Britain, by u/Domini_canes.

Hope this helps!
