I would recomend looking into the subject of japanese sabotage
Btw, are you aware of the japanese car mafia and the threats they made when Pakistan was giving a chance to the new car manufacturers? The only reason we dont see any competition is because of them
Bhai jaan maybe you need to reassess a little bit. Japan is perhaps the most peace loving country since WW2. They didn't even retaliate when North Korea was testing missiles that flew over them and fell on the other side of the ocean.
Also the Japanese car monopoly is due to the failure of our own policies. Everyone likes making money and who wouldn't want to exploit a situation where they are the sole provider of a product. Our leaders should have foreseen this back in the 70s and opened up the industry to others.
We need to learn from the Japanese and acquire new technologies from them through ToT. Japan probably wouldn't have the extra billions lying around like China, but they can provide us with new modern industries that may take our country to the next level.
