No, you can't

"War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feelings which thinks that nothing is worth war is much worse. " This sentiment did not make John Stuart Mill a warmonger; rather it clarified the definition of courage and truth. Obviously doing nothing is an alternative to fighting for what’s right; Actually choosing inaction is preferable to crusading for a wrong. To satisfy justice, however, there should be no bowing to the lukewarm or the fiery sword of an aggressor. Why did the lawyer who defended Leopold and Loeb in their murder trial of Tommy Franks at the beginning of the 20th century, quibble over the distinction between mental illness (his defense of his clients) and insanity? The killers’ actions spoke louder than any choice of words and their decayed and degraded state of moral and patriotic feelings qualified them for swift and sure punishment. Their trial became a mini-war between the prosecution and defense of right vs. wrong, justice vs. injustice, the fight to support what’s good about the gift of life vs. what’s evil and snuffs it out. World Wars, limited wars, civil wars, tribal wars, revolutions, jihads, ethnic conflicts, cleansings, plunderings, purges, rampages - all are ugly things. Mill knew that uglier still would be the impulse to say to an evil aggressor, "Yes, you can."
