In 1984 the premise was at least plausible as Americans perceived the Soviets were stronger than they were. But the NOKOs? Really?
How about this. Teenage children of investment bankers from the Manhattan are forced to use Krugerrands to buy toothbrushes as Chine.. err.. Asian bankers take over Wall Street in the new blockbuster: Red Debt.
It's just a movie, after all. But I think many people have a mistaken view of the North Korean armed forces.
Our government doesn't have the integrity or gumption to stop the slow motion invasion by illegals that is taking place right now.
How would they deal with an invasion by the NORKs?
North Korea has a standing armed force of about 1,100,000, a claimed reserve of more than 8,000,000 and a paramilitary force of about 200,000. Their standing army is well trained, well armed and tough (Just ask the US vets from the Korean Conflict). The paramilitary forces are armed units that are not considered part of the formal military forces. As a comparison, the US has a standing armed force of about 1,500,000.
The concept of the movie poses an interesting dilema. How would the US government fight a large army ensconced in US cities and heavily populated areas? Would they be less or more concerned about collateral damage (civilian casualties) from fighting within the USA as they are in the mideast? Would every cartridge and shell fired, every missle released have to be approved by a JAG lawyer? Would the same restrictive rules of engagement apply?
Initially the US forces are probably better prepared and situated to defend Europe than defend an attack and invasion on our own sovereign territory. That is not to say they would't adjust rapidly - but the idea that fighting the NORKs would be like fighting the Duchy of Grand Fenwick are not realistic.
