Gerard Vanderleun has an excellent essay you must read on cosmopolitanism,
American Perversions: The Not-So-Great Generation and the Vision That Dare Not Speak Its Name
This “vision” does not merely seek the defeat of America, but something much more essential to sustaining the rising tide of freedom across the globe. It seeks the defeat of the American ideal. And it seeks it while perversely claiming that it is here to “rescue” it by facilitating its defeat; an Orwellian apotheosis of stunning assertion, and one that will do more than anything else to advance the level of Global Warming to thermonuclear levels in one brief, shining afternoon than any other philosophy you can recall or imagine.
Global thermonuclear war is of little matter to those whose vision dare not speak its name. They believe, they deeply believe, that with enough talk and enough retreat, and enough appeasement, and enough money, and enough bribes that it will never come to that. Of course, it always does come to that, but this time, they assert, “will be different. We promise.”
At bottom, believing that a butcher’s bill will never come due, the destruction of the American ideal is really just fine with these “citoyens du monde”. They yearn, from their perches in their perverse cosmopolitan realms, to see their nation defeated and humbled and lowered. They yearn for it because they long ago left that nation and ascended into those ethereal realms of their own private Fantasy Island.
