Two very different scenarios. From what I learned Japan as a whole was in support of the war-- Syria and Iraq certainly do not; they are being harassed by a terrorist group, so your solution is to just blow them up, innocent civilians and all? Yea, we certainly haven't ended enough innocent lives there yet. Do you even know how much land area nuclear weapons destroy? Because it certainly isn't enough for a single bomb to take care of ISIS with how spread out they are, all it would do is clear a city.

WMDs aren't meant to take down unorganized terrorist groups that are bent on destruction, they are meant to destroy cities and cripple nations during war time. A nuke would not stop ISIS, a stable government and political borders that actually make cultural sense would.


Hiroshima and Nagasaki weren't very hard decisions either; those bombs saved more lives than they ended had the war continued.
