Been done before in RED DAWN (1984)
The idea has been done before multiple times, I've seen it before in RED DAWN(1984) starring Patrick Swayze and C.Thomas Howell with Ben Johnson in a miserable role, Ron O'neal is terribly miscast, and the rest are sobbing for good story. Extremely dull and very depressing. The same here goes to Amerika.
Only one movie treated the soviet case fairly and politely with a comic and humanistic touch, that movie was "Moscow on the Hudson" starring Robin Williams.
