If 300 of them decided to enter your house, illegally, uninvited, use your water, electricity, eat your food, borrow your car, run up the phone bill, use your credit cards to fraudulently make purchases, maybe one of them rapes your neighbor, as another 200 enter her house uninvited, she goes to the hospital and has to wait in line behind 200 more illegals, and then, each month the government comes along and tells you to pay for all this.
If this is not an invasion, what do you call it Jim?
A Joe Hadnuf paranoid fantasy?
This invasion is a bit like the story of the Goths. First, the Romans just let them in since they figured that they were not a military threat.
Things went bad between the Romans and the Goths.
Rome was looted.
End of story.
