Is there are any Church teaching on this? I often discuss the dropping of the atomic bombs (on Japan) with other Catholics. I’m against the dropping of the bombs because the Church gives clear guidelines on this. But sometimes I hear other Catholics saying that whilst these teachings (must discriminate between military and civilian targets and the all the rest of it) are important, they are overturned if one has no other choice but to let evil happen and thus one should go for the lesser of the two evils.
Should I be saying here the the dropping of the bombs could never be called a lesser of two evils? Or is there some teaching on this?
