Redefining someone's actions as "policies" is not any form of moral, ethical, or practical argument.
Bin Laden was supposedly very polite. He's universally considered evil for his policies. Putin is urbane and sophisticated - it's his policies that make him evil.
Civilized people were enraged by Trump's deliberate separation of children from their families. Surely you would not argue that this was OK because it was "policy"?
The Iraq War killed hundreds of thousands of innocent people, more Americans than 9/11, crippled a million people including 50,000 Americans cost literally trillions of dollars, had no planning whatsoever, and was based on a pack of obvious lies that had been exposed before the war even started.
In your "real world", the Rape of Iraq was completely inevitable. No moral responsibility accrues to any of the "leaders" who organized that war. In your "real world", there was no alternative to starting that complete and utter failure of a war, a war that lasted 15 years and got nowhere.
But in fact, you are the one who lives in an idealistic fantasy world, but it's a psychopathic fantasy.
If just a few of America's "leaders" had stood up and told the truth, there would have been no war. If there had been the slightest consequences for the cheerleaders of any of America's broken wars, you wouldn't have murdered literally millions of completely innocent people in my lifetime, including two million in South-East Asia along.
Your ability to just wipe away all the moral responsibility for war crimes with a wave of your hand is morally depraved, your reasoning is bullshit, and your immediate jump to a personal insult is the shit icing on top of the shit cake.
No claps for your intellectually and ethically bankrupt comment. I would be ashamed to be you, but then I am not morally empty.
