Well said. Very well said.
If there are just wars, then the rules of a just war, properly executed, are also just.
We know from following Homer Simpsons extensive posts about the end of WW2 in Japan, that the US warned Japan ad nauseum about the consequences if they persisted in waging war.
This was just and well done by us.
Likewise the rule of a just war is to minimize loss of life. America did this by dropping the bombs on two separate occasions, following lengthy delays and repeated warnings.
On ALL counts the Americans conformed to the rules of war in a just war. They thus saved at least a million lives.
Would that the heathen German and Japanese had observed the rules of war, and the theology supporting it, as well as the Americans did. If so another ten million could have been spared death.
