While it is true that the fire bombing of Dresden was every bit the war crime that you say it is you are incorrect that there was an option of "destroying military infrastructure".
The technology that existed at that time rendered such a strategy completely ineffective and the allies did try it with their strategic bombing campaigns for 2 years and it was largely ineffective.
The real reason why Dresden is so problematic is that the war was already effectively over by that point, sure an argument can be made that the allies were not totally convinced of this fact and it could be argued that the effect of the Dresden Raid did hasten the end of the way by about 3 - 6 months but given where the war was in it's progress there was no reason to target a civilian center that way.
