YOU CAN'T FOOL ALL THE PEOPLE ALL the TIME
"You can't fool all of the people all the time." Every so often abusive authority stirs a "slave" revolt wherein the people rise up against their oppressors. This process happens when the balance of forces shifts from fear of the oppressors to appropriate collective rage resulting in an unstoppable revolution.
At such times the people most affected by this process cannot reasonably hope to enlist the aide and succor of surrounding countries who se leaders more often than not have their own abusive authoritarian governments to protect.
For example, if China was to come to the aide of the people revolting there would be an understandable and predictable concern by the Chinese government that those in favor of democracy might well use this support as encouragement to stage their own protests. (Note the history of Tibet.}
Thus those who participate in open rebellion against rulers who abuse their authority must be aware that they can be and often are slaughtered. But it is equally true that those who govern do so at the collective consent of the governed.
Human beings prefer freedom to oppression except for those who prefer to control everyone else except themselves. Those who rule by fear initially have the upper hand but only so long as the "slaves" cower. Let the "slaves" unite and the oppressors will eventually and inevitably be crushed.
