The natural, instinctive reaction to abuse is revenge. Civilization requires taming many instincts useful for survival by hunters/gatherers, including the urge for revenge. Aggressive war is one of the worst and ugliest forms of revenge, but in “modern” society most of us are far removed from war’s realities when the war is “over there.”
Many movies do the best job possible in confronting us with the individual, personal tragedies of war for those of you who only experience it on TV news. I have no doubt that if more people understood the nature and consequences of war, they would advocate it far less often.
One of those movies you should watch is Golda. Golda Meir was the Prime Minister of Israel during the Yom Kippur War of 1973. It very well depicts the pain, confusion, and tragedy of war (in this case an attack on Israel by Egypt, which Israel obviously could not avoid). We watched it last night and cried yet again.
