Why was Joseph stain successfull

I hope your talking about joseph stalin...

Beside pure luck, Stalin possessed several qualities that are be indispensable for anyone with the ambition to lead a movement for radical justice.

Firm belief in the supremacy of totalitarianism above democracy and the economy based on private property
Clear understanding of the national cultural code and the Machiavellian principles of state power
Constant learning, combined with critical judgement and superb memory
The “Putin pack”, indispensable for secret operatives: tenacity, attention to details, cynicism and obsession with secrecy. (Many people call that “paranoia”. They don’t realize how important is this “pack” for balancing off the huge personal ego needed for grabbing and retaining power.)
The Soviet poster below shows a Soviet man who seemingly combines the high energy level, ambition, the ability to observe and learn, and the rest of the skill set that ensures success to a true warrior of radical justice. Caption: “Be vigilant!” Rhymed text of the proletarian poet Mayakovsky: “Comrade, don’t indulge yourself in the days of peace / Toss away your affability / Comrades, remember: the class enemy / is operating among us with all he’s got.”
