I would note that the list misses the nice slight of hand when Napoleon sold a great deal of land to the United States (the "Louisina purchase").
Which puts to mind the Royal Navy's shanghai of American sailors and the British Army's burning of Washington. Stark contrast that.
So, rather than the cultural basis (language, origins of law), exactly what did the British do to help the Americans?
Actually, it was the better French food and wine, I'm sure (that why the Californians helped to restart the French vineyards). - R
PS - It's OT, still Lieutenant-Colonel Charles E. Stanton said "Lafayette, we are here" (not Pershing). - R
