Firebombing cities was a thing. There is little difference in firebombing Tokyo with 200 planes and dropping one "special" bomb. Second bomb (Nagasaki) was not authorized in some special way. Air force had two bombs available and planned to drop them a week apart. Due to weather it ended up being 3 days. After Nagasaki Truman ordered them to need explicit approval of the president to drop future bombs (appalled at civilian deaths).
