It's hard to tell….
But France wins for one reason: Paris, the most romantic place on earth. Italy is very romantic (Venice), and some would no doubt give it the number one spot, but for me Italy has so many other characteristics that come to mind (Art and Renaissance History, Bloody Roman Imperialism, Modern Mafiosa Legend, Unfortunate World War II Axis alliance, Seat of Catholicism) that it has to be France. France has 2 images in America: Pure Romance, and Rude to Americans. Even rednecks who hate France for political reasons understand instinctively that Paris is the height of Romance !
