You had more than a little help from the French remember.
In early 1778, shortly after an American victory at Saratoga, France entered the war against Britain; Spain and the Netherlands joined as allies of France over the next two years. French involvement proved decisive, with a French naval victory in the Chesapeake leading to the surrender of a British army at Yorktown in 1781.

Do you think that if those 3 nations had kept out of the fight that the USA would ever have existed ?? I doubt it.

Funny that with all that help from France ,Holland and Spain that America still retains English as it's preffered language.
