1. A German imperial agent planted into the highest echelons of Second International Marxism substantially contributes to Leon Trotsky‘s theory of permanent revolution and helps smuggle Vladimir Lenin out of Zurich into Russia following the February 1917 revolution, thus paving the way for the glorious October Revolution that same year.
2. A Soviet double-agent planted in the highest echelons of the US financial establishment helps devise the Bretton Woods system, fastening international currency to the gold standard and thereby saving postwar capitalism from itself (until the rise of stagflation).
