How to make the United States civil strife and make it like Syria?

Personally, I think that a country like the United States, which has no national history (unlike China, which has thousands of years of national cohesion, which enables China to maintain overall unity in the face of any disaster, and of course there are a few traitors in the past dynasties) relies entirely on its own strong economy, and its citizens come from all countries and races in the world, so there is no sense of national unity, and people who immigrate to the United States are only full of yearning for a better life. In addition, the economy of the United States is supported by monopoly capitalists, the politics of the United States is heavily dependent on capitalist consortia, and the powerful military of the United States also depends on monopoly capitalists. Therefore, as long as the American economy falls into a long-term depression, this melting pot will naturally collapse. However, according to the landlord, there is no basis for civil strife in the United States, at least for now. The demise of the United States is either conquered or disintegrated by itself.
