What made the American Revolution succeed through violence were the facts that (1) it was a war of attrition against a foreign, remote power, and (2) it was bolstered by another foreign, rival remote power. Due to its far-flung nature, it cost British Empire a LOT of money to keep the war effort going, and moreover at a time when they were hurting for cash (since this was just after the Seven Year's War with France). The Americans and French were able to make it too costly for Britain to continue to hold on to the colonies.
Britain also tried to take America back in the War of 1812, but was again thwarted by the costs of maintaining a war abroad (and the war had come to a stalemate by 1814).
Unlike most revolutions we see today (which are revolutions at home, and become civil wars if they turn violent), the American Revolution succeeded through violence because it was against a foreign adversary and because the Americans were able to make it too costly for Britain to maintain their war effort. These preconditions do not apply to local revolutions, where no side has an economic incentive to stop fighting until the other sides are crushed. Each factions' lives are on the line, largely eliminating the cost consideration. It's not like King George III or the members of Parliament were in danger of losing their lives, families, and lands if the Americans won.
