I think I would substitute do-gooder, rather than either idealist or adventurer, or combine all three adventurous idealistic do-gooder

and I would probably add the word only to the phrase "with only a touch of Marxism", or "hardly any marxism"

Of course, to an american audience, Describing him as a modern-day George Washington, would probably also conveh the intention of the original passage.
