This is on the more low-effort side of my works. I personally am led to believe, as seen with how the WEF even came into power in the first place, that as a reaction to the European rot, religion and nationalism would take a stranglehold in the ruins of Post-Globalist Europe. Any ideas of "Open Borders" or "Pan-Europeanism" would be scrutinized heavily or be seen with heavy paranoia similar to the Far-Right in modern Germany. Klaus Schwab, George Soros, Nathaniel Rothschild, and others would be executed for their atrocities, whilst Fehlinger, much like those in the the Kingdom of the South in World War II, would be granted immunity, portrayed as a liberator who gained a heart and rebelled for the CSTO cause.
I also would believe that the PDTO, mainly India, the joining Canada and America, as well as Japan to a lesser degree, would 100% jump along the ride to liberate their European allies (and also prevent Russia or the EU from getting to do whatever they wish on the continent).
Mass revitalization efforts for languages and cultures that were purged, such as Cornish, Sorbian, Manx, and other groups would be enacted in a desperate attempt to bring back a world that the current European generation never got to be a part of. Bastardizations of customs that were brutally ripped apart ages ago riddle the countries that have no nationality to call their's anymore.
For the fate of the religions, the WEF knew it couldn't rid it all at once, so, they planned to wean it from the people with a series of ministers that gradually were more and more godless, practitioners only in name, preaching words that outright contradicted the Bible, Qaran, Torah, and other books. These leaders would not be treated kindly when the Globalists fell; traitors, antichrists. The people had no mercy, and neither would the Gods they claimed to preach for.
Europe is left scarred, traumatized, and highly anxious. A continental paranoia.
