I would settle for an orderly exodus from the Titanic. America is otherwise on a decline in terms of hard and soft power, and that's the best that can be hoped for, to minimize damage to actual human lives.
Of course, many Americans don't want to hear hard truths, and that's part of what has fuelled the rise of extremist politics in the US in the first place. People prefer fantasy in the US: we are the home of Disney and its associated American-style utopianism, after all, as documented in Stephene Fjellman's work, Vinyl Leaves.
Trump has made Evangelicalism front-and-center, so the damage he has done is truly unique.
Many Evangelicals (and even non-Evangelical Christians) were fine with that gamble, too, which shows a lack of moral education on the part of many Christians. As Jesus said, "Don't give what is holy to dogs". Prostituting your religion shows you aren't serious about it in the first place.
