I think ultimately, any nation...including my own, must draw on the lesson of Hiroshima and Nagasaki. Lesson being that once you engage in total war, there can be no guarantee as to its conclusion.
Better not to make war, but once it is entered into, wage war with complete certainty. Destroy those that you war against as completely as humanly possible while maintaining your own ability to exist.
To the Japanese civilians that died as a result of the atomic bombings I feel compelled to pity them and greive for them, but war is what it is. Death and destruction.
Better not to make war than to do so. Avoid if at all possible.
