I know because I fell into my own internet rabbit hole about 20 years ago, and saw the entire plot laid out in detail. The invasion will come from all sides, Asia, central and South America, and Europe, unless the country somehow manages not to fall into the trap of being the nazis of the 21st century, which would entail the right in this country calling bs on trump and getting rid of him for a more moderate politician. Right now that looks unlikely and with the rhetoric of retribution surrounding this has both sides being pushed into civil war, it looks like we might do our would be conquerors a favor by defeating ourselves.
