Remember some stories, sure. But in 20 years, the context of those stories could have significantly changed under propaganda pressure from the Empire. Consider the idea that a xenophobic government, in the aftermath of a war largely against aliens where many people are grappling with tremendous amounts of economic difficulty, might use those factors to come to power, seize the media, order a dictatorially-run and oversized military around to suppress dissent, and manipulate the public. The Nazis turned the German public and the fringe anti-Semitism there into a genocide machine behind a monomaniacal cult of personality in less time.
Granted, there's a vast difference in scale - but then understanding the immensity of the Republic/Empire/New Republic and space in general has never been the series's strong point.
