Pope Francis on Sunday said defence must "always be proportional to the attack" - when it is "disproportionate", it shows a tendency to "dominate that goes beyond morality", replying to a question on air strikes on Lebanon and the conflict in the Middle East. The pontiff stressed that the actions undertaken by "a country, any country" which uses "force" in "such a superlative way" are "immoral". "War is immoral but the rules of war indicate a morality", "when this cannot be seen we say in Argentina, bad blood", the pope said, speaking to reporters on a flight taking him back to Rome after a three-day visit to Belgium.
