The appearance on Russian state television only lasts a few seconds, and the effect should be shocking.

Where do these Russian women and men get the courage to ruthlessly risk everything for their own fate?

There are already so many.

Like Marina Ovsyannikova, who jumps into the live picture during primetime news with her self-painted poster - for a few precious seconds in which she conveys her protest to the Russian television people before the station reacts - and shuts down.

Mariana Ovzyannikova is now in prison while her second, pre-recorded appeal against Putin and his war spreads millions of times online.

Hug me!

Or like the Russian woman, bent with age, who announces her resistance at night in Saint Petersburg and is taken away by police officers who could be her grandchildren.

Elsewhere, a young man holds a sign that reads, "If you're against the war, hug me!" Passers-by can be seen looking around nervously before hurrying to do so and flee.

In Nizhny Novgorod, a young woman is taken away with a poster whose action is particularly ingenious: the poster is empty, just a white space.

Of course, the Russian state power understands that this is something like the original text of the protest.

When the historian Timothy Snyder wrote "On Tyranny" in 2017 under the impression of the Trump election, his "Twenty Lessons for the Resistance" became a world bestseller.

Translated into numerous languages, the volume is still not available in Russian.

What some considered overly alarmist at the time turns out to be visionary in retrospect.

Just read Snyder's remarks on Putin.

The Russians, who are now rehearsing their resistance at the risk of their lives, may have taken note of the book in other languages.

But we, the spectators on the sidelines on safe ground, can also find help in it.

Some things read as naively as formulated for a children's book - and that's how the book with the illustrations by Nora Krug is also presented: "Don't show hasty obedience" is Snyder's first commandment.

Then follow demands like: "Defend institutions" because they cannot do it themselves;

"ask and verify";

"talk to others";

"be patriotic";

"keep calm when the unthinkable happens".

Many of these calls seem like civic micro-actions that we should all be able to implement.

But it's not as simple as that, which is why Snyder gives his last lesson the utmost urgency in its brevity: Be "as brave as you can."

However, this is followed by the terrible realization: "If none of us will die for freedom, then we will all perish under tyranny."
