In Russia, you only fuck up once

The head of Russia's GRU military intelligence agency that the West has blamed for a string of brazen attacks [Igor Korobov, 62, who ran the spy agency since 2016] died on [November 21] after "a serious and long illness," the Russian defense ministry said.

Britain has accused the GRU of attempting to poison former Russian spy Sergei Skripal and his daughter with a nerve agent in the city of Salisbury.

[...]

Speculation about Korobov's fate had been growing since an unconfirmed Russian media report that he had been summoned by President Vladimir Putin after the Skripal affair and severely criticized for the operation which left the Skripals alive and the GRU a target of mockery in the Western media.

[...]

Asked last month if there would be a shake-up at the defense ministry in the aftermath of the Skripal affair, the Kremlin said the low quality of the allegations leveled at GRU did not justify such changes.

And what a coincidence: Korobov is dead, so now they can put someone else in.

Putin may be Stalin's heir.

...but hey, do what you want...you will anyway.
