Putin himself explained his resignation by his disappointment during the collapse of the USSR and the security bodies. In his words “he felt that the country no longer needs him”. Possibly both versions are right: Putin was disappointed with the KGB and the KGB was disappointed with Putin, there was no need to promote an average officer. And if the rumors about Putin’s early failure in Bonn in 1975 are true, then the unmasked and arrested agent was rejected from the start, he could not be used in capitalist countries, he could work only in socialist countries and therefore was not worth much from the beginning.
