Their schematic:
1. Use race, culture, and class divisions to cause civil unrest.
2. Relax immigration and border control to facilitate rapid demographic shifts, provide potential for vote fraud, and decrease US wages - leading to dissatisfaction with capitalism.
3. Use central control in Communist / socialist nations to provide cheaper labor - allowing those nations to outcompete the US industrial base.
4. By doing #2-3, decrease opportunities for American youth - making them more susceptible to anti-capitalism sentiment.
5. Ramp up anti-capitalist pro-Communist propaganda / indoctrination in schools/universities, and wherever possible in media and entertainment.
6. Simultaneously label anyone supporting capitalism, voicing opposition to open border, or opposing the left a fascist (use that word and other terms (imperialist, white supremacist, racist, bigot, homophobe, xenophobe etc. as derisive labels for anyone in the opposition.
7. Dilute the power of religion as a guard against socialist / communist takeover (label religion as anti-science, anti-gay, regressive, etc.; work to infiltrate the hierarchy of the Catholic Church such that a figure such as a Pope JohnPaul II type figure is removed as a potential threat to socialism/Communism).
8. Use the tenets of religion (generosity, self-sacrifice, kindness, helping those in need, not turning away those with unmet need etc) to shame Americans who oppose open borders, mass immigration, and socialism / Communism.
9. Promote policies that increase inflation, thus diluting the accumulated capital of the middle class and promoting dissatisfaction with Capitalism.
10. Link democracy with socialism (e.g. social democrat).
11. Work to socialize as many institutions as possible.
12. Infiltrate a political party, take it over, push socialist / Marxist candidates.
etc. etc.
13. Develop a violent protest wing that can be used to oppose law enforcement, shut down any deportations, and violently suppress oposition groups (e.g. Antifa).
etc. etc. etc..
Russia and China would just love that. This cancer has to be irradicated here and soon. It took Venezuela less than 10 years to become a third world outhouse.
