Socialism

In the preface to the 1882 Russian edition of the Manifesto, Marx and Engels say that the Russian commune could “pass directly to the higher form of Communist common ownership” only if the Russian Revolution (which he saw as inevitable, though it was not inevitable that it would "take[] place in time" (first draft of letter to Zasulich), and in the Letter to Otecestvenniye Zapisky he says that if Russia continues on its path, it will have lost this chance to skip the phase of capitalist development) is supported by wider revolution in the West. Otherwise, the Russian commune “must [] first pass through the same process of dissolution such as constitutes the historical evolution of the West.”

There’s zero approval by Marx here for the notion of skipping the phase of private production/property in one country without a wider revolution.

Marx told Zasulich at the time that education was one of the most crucial factors in the possibility of bypassing the agonizing stage of capitalism.

No he didn’t.
