After the end of World War II, the world landscape changed dramatically, with the United States and the Soviet Union becoming two superpowers. The two camps, led by the two superpowers, also fought for a long time, culminating in the outbreak of the Cold War between the two superpowers in 1947.
In their Cold War, in addition to direct war, the two countries also used many means in the struggle against the enemy countries, especially in the field of intelligence. Intelligence determines whether the war is successful or not, and the CIA tries its best to grasp the Soviet Union's every move.
In addition to the most common spy personnel, in order to better investigate the situation in the Soviet Union, the CIA came up with an unprecedented plan called "Eavesdropping Cats" The move was to perform surgery on the cat, install a bugging device on the cat, then put the cat on the enemy's territory, and then use the components inside the cat's body to transmit intelligence.
This operation is very cruel to cats, inhumane and a serious violation of animal protection laws. But at that time, no one cared whether the cat was in pain or not. They installed bugging devices in the cat's ears, signal transmitters and batteries on the chest, and antennas embedded in the spine.
Such surgery turns the cats directly into a movable bugger, but that's not all, because the hardest part is how to train them to be qualified buggers. The CIA spent a total of five years and invested $15 million in the implementation of this plan.
After the training, the CIA couldn't wait to release the cat. But before it could exert any value, the cat that was released had already been hit by a car and died tragically on the street. The CIA was not reconciled, and then released the other waiting cats to eavesdrop, and all failed, and the cats that had not been eavesdropping could successfully complete the task.
In fact, this plan sounds very unreliable, even if you want to train, don't you have to train some well-trained animals? What brain circuits make them choose a cat owner?
