Street protest, if it can sustain itself for more than that crucial first week, has an effect that is both tactical and emotional; mass protest during the French Revolution made it clear to the courtiers that this rebellion would be too profound to quell in the usual manner; street protests in the American colonies, in the face of arrest or worse, made the colonies ungovernable even before George III waged a costly, unpopular war. In Estonia in the 1980’s, the small, illegal protests that surrounded the public singing of the banned national anthem grew, and Estonians were emboldened as their numbers swelled by the thousands daily.
