What did the US do to Toshiba when Japan's Toshiba stole and sold precision machine tools to the Soviet Union?

At that time, the US Congress passed a sanction agreement for Toshiba, such as imposing a huge fine on Toshiba of Japan, amounting to as much as $15 billion. And it more than doubled the tariffs on Toshiba's imports in the United States. So this has caused a very big disaster for Toshiba Japan, and has caused Toshiba's share price to fall severely. It even led to the resignation of the chairman of Toshiba Japan.

The main reason was that Toshiba was exporting precision machine tools to the Soviet Union for the development of propellers for nuclear submarines. So this would make the Soviet Union's propeller technology reach a very high level, so that at that time NATO countries did not have any sonar to detect the Soviet Union's nuclear submarines. So it also posed a very big threat to the NATO countries. Because the Soviet nuclear submarines have a lot of nuclear missiles on board, once launched like the Western countries mainland, it will cause a very big nuclear pollution and radiation.

So the NATO countries blamed Toshiba, and many Japanese people thought that Toshiba was a traitor, openly supporting their enemies. So it also made Toshiba's products firmly boycotted by the Western countries. This also caused Toshiba to once face the risk of bankruptcy. So it has also led to the fact that the Tokyo-based company has been in a very depressed state now, and the Japanese government has also filed a lawsuit against Toshiba.

Let's look at the background of this in fact is because in the United States and the Soviet Union to compete in the Cold War stage, so that both sides are in a state of confrontation , however, the United States and these countries are prohibited to the Soviet Union to export the development of military weapons equipment and production equipment, but Toshiba is openly to the Soviet Union to sell the development of military equipment equipment equipment, which has led to NATO countries for the detection of the Soviet Union's nuclear submarines, but also led to the development of a nuclear submarine. countries to the Soviet Union's nuclear submarine detection was ineffective.
