It could butterfly away the American revolution, but it would be more interesting if it merely butterflied away French involvement in said revolution.
And even more interesting: still a revolution, and still a success,
the first one is unlikely (as the colonist would see the use of their taxes in the troops needed to fend of the French) but may be possible, if London abuses the colonies enough. The seocnd is just plain ASB; no french involvment means the revolt dissolves for lack of funds and supplies.
