My purpose was not that Japan is not intelligent! I never write such offensive things about others. That was just a suspicion.
Japan is the motherland of new electronic technology ( Transistor and IC inventions) and also its other industries are excellent, among its car industry that sometimes is higher than American and European cars such as Ford, Mustang, Chevrolet, Jugular, Fiat, BMW, Audi, Peugeot, Citroen and other brands (Except Benz ! In my opinion, It is the best brand in the world. I love it very much and always wished to have a Benz, even a lower model, but sadly I hadn't enough money to buy one ).
However, Japanese engineers are among the best experts in the world, and Japan industries are among the bests as well.
But sadly the political system of Japan is under license of U.S and is dependent. Japanese are not free to decide solely and they have to follow America policies.
For example, when Iran was defending against dictator Arab, Saddam's army that had attacked to western borders of Iran (that unwanted war was called, 8 years holly defense), we bought a series of Toyota vehicles from Japan for defensive fronts. But sadly Japan left us alone suddenly and didn't sell those vehicles to us, based on order of America politicians.
Japan was the first country that participated in the unjustly economic sanctions against Iran, in that critical situation ( I have not forgotten that disloyalty of Japanese politicians up to now).
Nonetheless, we were not desperate and drove out Saddam's army from our borders strongly (Saddam had the most powerful air force and armored forces in the area at the beginning, but in the end of the war, he lost a notable of his forces and became desperate).
In that unjustly economic sanctions, the only country that didn't break up his trade and economic relations with Iran was China.
I also don't forget the economic and trade companionship of Chaina with Iran. This caused, God increased their wealth to reach this point of economy prosperity.
