It is not yet known how big the betrayal is that the now arrested BND employee is said to have committed.
He is suspected of being recruited by a Moscow secret service.
It's been a while since a double agent was exposed in the BND.
It shouldn't surprise anyone that such cases exist.
Secret services don't just want to find out what the enemy knows.
They also want to mislead him.
Even in the age of cyber espionage and satellite reconnaissance, human sources have not become superfluous.
Putin is a former KGB man
The Russian services in particular should also be convinced of this.
At the head of the Russian state is a former KGB man who made a career in this notorious organization over the past century.
In Russia they say: Once a KGB, always a KGB.
Since he first became Russian President, Putin has filled many top positions in government and business with intelligence veterans.
If Putin is going to rely on anyone, it's on these cadres.
Under him, Russia has become a secret service state – whose unscrupulousness and willingness to use violence can be expected at any time, as BND President Kahl said.
Putin is waging a war in Ukraine that threatens to turn into a disaster for his regime because the country that has been invaded is receiving massive support from the “collective West”.
The Kremlin is trying to weaken it with non-military means wherever and however it can: by spying on politics, business and society, through disinformation and cyber attacks.
The exposure of the alleged double agent also shows the general public that Moscow is waging a secret war far behind Ukrainian lines.
In Germany, too, one should therefore remember NATO's motto: vigilance is the price of freedom.
