Revolution is the overthrow of one class by another. What occurred in France, Russia, and a number of anti-colonial national liberation struggles throughout the global south for instance. The OP is of course being facetious (can’t blame them, Americans are frustrating in their servitude and passivity despite what’s unfolding), revolution doesn’t occur unless the material conditions are conducive to mass disobedience on that scale. The problem is that liberals are trying to funnel the disillusionment and contain it in hopes of dissipating the revolutionary moment in order to get back to their usual business of putting a human face on America’s domination and hostility in South America, Asia, and Africa as the “Good Cop” to the Republican’s “Bad Cop”.
