If American independence had not come in 1776

How might history change if the American colonies had not become independent in 1776?

Independence likely comes later; a continuing external threat might make British protection and taxation acceptable long enough for an early dominion-style settlement.

Independence would probably still arrive eventually, but its timing and form would depend on later wars and perceived threats. If Spain replaced France as the principal danger, colonists might accept taxes as the price of British protection. North America could then develop as an early self-governing dominion. Whether it became one larger state or several nations would require economic, social, and cultural analysis beyond a quick naval answer.
