A video coherent argument about a worldview that is perverted, under the argument. View it, and note how coherent the presentation is, and how the ideas, call them that, which she critiques are not on solid ground. There is the biblical myth about feet of clay, and she's looking at feet in her commentary.

Heather Cox Richardson on would-be dictatorship musings spoken boldly in a quite pubic place.

It seems her historical factual assertions are not open to sensible debate. She recites how a world order was conceived after a devastation worldwide by war - one fought then with weapons well beyond those available to nations now, vs then.

Her underlying premise is giving up the world order in place is a bad idea unless done as an improvement, and whether that or backsliding is a question of looking at today and judging.

Her quotations from Trump's speech before the UN, are on record, there can be no debate over the words he spoke. They are all over the Internet, in video, and transcription is easy to show HCR nails the exact words Trump used. 

The HCR analysis hangs together to where everyone should hear and see it through, and then think it over. To Crabgrass, no problem saying, "She nails it," but others might see grounds to argue she's wrong.
