Why the Royal Navy treated the American wars as secondary theatres

The American Revolutionary War and the War of 1812 are treated here as secondary naval theatres within larger struggles against France and its allies. During the revolution, the American naval force itself could not impose the decisive pressure later supplied by French intervention. The Royal Navy therefore concentrated better ships around Europe in an effort to contain French power, even though that choice created risks elsewhere. That naval priority is separated from the British Army's responsibility for the land campaign, where stronger focus and leadership might have mattered more. The point is about theatre allocation rather than the later importance of the United States: navies distribute scarce strength according to the enemies they regard as strategically decisive at the time.
