Considering the size and enthusiasm of the revolutionary movement the only way it could have been beaten would have been a combination of vigorous and aggressive conventional military operations connected to heavy handed and deliberate terrorization tactics involving extensive deliberate destruction of private and public property. This is basically what the US government used as a strategy to defeat the southern rebellion and this effective terrorism engaged in by Sherman and Sheridan and a host of lesser lights is routinely hailed both here and in the usual conventional nationalist texts as a mark of the wisdom and sagacity of the Union high command.
British efforts along these lines were scattered and unfocused but even those put a real fright into the American rebels. The Wyoming and Cherry valley raids and Arnold's operations along the Connecticut coasts and later in Virginia are mentioned with a shudder in many conventional American accounts of the Revolution. Walter Butler was probably correct in reportedly trying to convince the British in Montreal to greatly expand his raiding force at Niagara and incorporate regulars in it so that raids such as the Wyoming Valley operation could be mounted into the heartland of the revolutionaries and capturing and sacking Albany would have a powerful effect on depressing revolutionary zeal in New York.
The leadership of the American Revolution was certainly more dynamic and just plain smarter than those of George III and Great Britain but their lieutenants on the ground were also just plain more focused and ruthless in terrorizing, defeating, and beating both the redcoats and the large loyalist community. These are lessons that would be well for the modern GOP and those who call themselves conservatives to ponder. The enemies of liberty this time are better organized and far more focused and smart and ruthless than their opponents and they will win unless confronted with people who are just as ruthless and determined and if necessary unprincipled as they are. The rats know what the American rebels knew “Winning is not just the most important thing , it is the only thing’.
Excellent, well-founded comments with multiple modern connections and parallels. Your final paragraph frames the current political context very well. Your view as regards “unprincipled” is certain to be controversial but that makes it no less vital a subject for discussion.
