If they don't work, there will be a reversion to, not communism which has failed, but what I call a new despotism which would pose a mortal danger to the rest of the world because it would be infected with the virus of Russian imperialism which of course has been a characteristic of Russian foreign policy for centuries.

使用する際の注意点

The basic sense is reverting (as nominalization of revert), but also used as reversing (from reanalysis as reverse + -sion), for which the more precise term is reversal. Compare “mean reversion” with “reversal of fortune”. The similar regression has connotations of moving back in time.

In the Islamic sense, reversion and revert, although popular colloquially, are objected to as illogical and inaccurate by many Muslims and some of Islam's authority figures on linguistic and theological grounds.
