Conrad's cartoon contains a big ironic twist in it. The bombers dropping the Japanese import cars are none other than multimillion-dollar Boeing 747s--surely each one costing the equivalent of many hundreds if not thousands of small Japanese cars. And if I'm not mistaken all of Japan Air Line's international fleet are Boeings and probably most of their domestic fleet also are Boeings. So they do indeed import something.
Maybe we have been trying to get them to buy products they really do not need at the present--like shoes, electronics, manufactured products, and paper goods. They surely can use our crude oil, wood products, meat and poultry products, seafood, grains, pig iron, as well as many products they now import from Asian sources.
