Those certainly were appalling and destructive events. But why give them some special status over other bombing raids like the March 9 fire bombing of Tokyo, which also killed over 100,000 people in one night? Dropping 1 bomb vs. dropping 1,600 tons of conventional bombs in 3 hours?

Your title would read better if you changed the second “against” to “of”, OP.

…and used them against civilians.
