John Rawls in his analysis of the bombing of Japanese cities by America at the end of the Second World War, turned to another important philosophical principle: the ends must justify the means and if they don’t the means must be discarded in favour of those that do. This was the argument made by another great philosopher this time from Canada and in fact from my university—Arthur Schafer. I hope to go into greater detail on this point in a future post on this issue but will just mention how Rawls deals with it. This is what he said:

“Finally, we note the place of practical means-end reasoning in judging the appropriateness of an action or policy for achieving the aim of war or for not causing more harm than good. This mode of thought—whether carried on by (classical) utilitarian reasoning, or by cost-benefit analysis, or by weighing national interests, or in other ways—must always be framed within and strictly limited by the preceding principles. The norms of the conduct of war set up certain lines that bound just action. War plans and strategies, and the conduct of battles, must lie within their limits (The only exception, I repeat, is in times of extreme crisis.”

In other words, war without genuine limits is never acceptable. Rawls, like Camus, and unlike Lindsey Graham and unlike Hamas, acknowledges there are limits to what one can do in a just war or it ceases to be just. Limits are not just important. Limits are essential to the just war. A war without limits, which so many wars in recent years have become, is not a just war.

Rawls insists that the defensive war must not cause more harm than good. In his view it really is that simple. He might be right.

I heard Antonio Guterres, U.N. Secretary-General interviewed by Fareed Zakaria and he pointed out that every year for 7 years he has published a report about children killed in wars. He has complained about countries like Syria, Russia, Israel and the Taliban in the past. None of them were happy with his reports. Until now he said, the most children that were ever killed by one country in such conflicts was 600 in a year. He also said that he did not rely on the numbers of deaths in Gaza presented by Hamas as they were not reliable, but he said,  “it is clear that the number of children killed in a few weeks in Gaza is in the thousands.”

Earlier he also said, Gaza had been turned into a graveyard for children.

Does the end justify that means? Thousands of children dead and of course, many more adult civilians, many of them women and old people?

I have a hard time seeing that as doing less harm than good.
