I voted for the second, third, and fourth options. But I do think that if our soldiers are operating under constant fear of investigation and court-martial for every little mistake they make, then we're bound to lose any war we fight.
I agree. We can't hope to win a war if we take all our options off the table at the outset.
There was no war more moral than WW II. Morality required that we fight it. And we had a policy of deliberately targeting civilians, in order to de-house them and demoralize them. Cloudy days that made it harder to hit military targets were called "women and children days" by the air force pilots. The famous firebombing of Dresden was undertaken specifically to kill as many civilians as possible so as to force the Germans into unconditional surrender.
I would rather win a war like WW II through means that may be brutal than allow monstrous evil to prevail. Sometimes, ugly choices have to be made. It is unrealistic to think otherwise.
