The walls around the besieged building were covered in angry graffiti that reflected this in the crudest terms. One, I recall, read “Rossiya, vyidi iz zhidomasonskogo OON!,” or “Russia, get out of the Judeo-Masonic UN!”

On October 4, 1993, White House rebels were crushed by Boris Yeltsin, brutally. They seemed to have been swept away into history.

That was not the case of course. The armed men in camouflage did not disappear, they relocated. Some fought in Russia’s wars in Chechnya. Others found a haven in the pro-Russian enclave of Transnistria, which had broken away from Moldova in 1992.

Under Vladimir Putin, the marginal narrative of blaming the West for a conspiracy against Russia became first acceptable and then mainstream. But Putin himself has always steered clear of the sensitive issue of October 1993, maintaining his double identity as both Yeltsin’s heir and anti-Yeltsin. Back then, after all, he was working for the pro-Yeltsin mayor of St Petersburg, Anatoly Sobchak and he doubtless approved of the crushing of a group of armed anti-state rebels.

Fast forward to Donetsk and Luhansk in 2014. The two main leaders of the Donetsk People’s Republic, Alexander Borodai and Igor Strelkov, are both Russian citizens who worked for the intelligence services, fought in Chechnya, spent time in Transnistria and worked for the ultra-nationalist newspaper, Zavtra.

There has been much debate about the degree of autonomy these men enjoy. In a persuasive article, security expert Mark Galeotti describes Strelkov as a “a loyal Russian well off the reservation,” speculating that he got involved in Crimea and Donetsk on his own initiative but has been coordinating his actions with the security establishment in Moscow.

Which brings us back to October 1993. Borodai was there. Writing for Zavtra, he calls the siege, when he was a “White House defender” at the age of just 19, the defining moment of his biography. He reflects that Putin’s regime lacks legitimacy because it is the successor of Yeltsin’s, but gives it some credit for correcting Russia’s course.

There is a growing and appalling body of evidence that suggests these men were responsible for the shooting down of an international airliner. Even without that, President Putin must know that they have become a toxic liability and that their views are sufficiently different from his own that they might resist orders to stand down.

In the longer run, Borodai’s and Strelkov’s agenda is to establish a “patriotic regime” in Russia akin to the one that failed to come to power in Moscow in 1993. Hearing their words, you get the impression that they would be happy to do so either with Putin or without him.
