Oh, the war dead, the economic waste in those endless wars, the loss of civil rights for Americans... the cost from Bush + Chaney was massive. No doubt. And leading the nation into such a war on the flimsiest of evidence was criminal. Especially when Scott Ritter, who would have been the first on the front lines to call Saddam a death-gas-peddling monster after how much he was refused access for inspection, said he had zero evidence and didn't believe any WMDs existed there anymore.
But that was deliberate deceit. That comes down to being just evil and calculating.
Trump, on the other hand, is a self-inflicted wound on America. The culmination of Tea Partiers who felt that smashing the system with a wrecking ball was always going to be a better approach than trying to work within the system. And so America elected a reality TV president. But one I have to invoke Hanlon's razor on. The guy isn't so much evil as he is pathologically mentally ill and the culmination of the Peter Principle.
You might say George W Bush wasn't a terribly great scholar of the world or the economy either, but he at least surrounded himself with knowledgeable, capable people. Evil people, yes. But at least rational ones. Trump disease is about surrounding yourself with an idiocy bubble of yes men. It is actually really comical if it weren't so tragic.
America is a very, very dark place in the world these days.
