Did you not even read your own source? Your quote doesn't appear in there at all. In fact there's multiple sections of this artivle that back up what I stated, as quoted:

Mr. Byrnes recommended, and the Committee agreed, that the Secretary of War should be advised that, while recognizing that the final selection of the target was essentially a military decision, the present view of the Committee was that the bomb should be used against Japan as soon as possible; that it be used on a war plant surrounded by workers’ homes; and that it be used without prior warning.

Or later:

...that the weapon be used against Japan at the earliest opportunity, that it be used without warning, and that it be used on a dual target, namely, a military installation or war plant surrounded by or adjacent to homes or other buildings most susceptible to damage.

Emphasis in both quotes were added by me.

If you're going to start throwing sources at people, you should at least fucking read them first.
