Well they both helped to modernize/industrialize the U.S, so it depends which view point you would like to take. They stole the plans from england, who had successfully monopolized industrialization for almost a century, who would be upset at this loss of control and therefore business. However an American would probably be thankful for the industry that blossomed as a result of these actions.
The development of the Napoleonic Code was a fundamental change in the nature of the civil law system, making laws clearer and more accessible. It also superseded the former conflict between royal legislative power and, particularly in the final years before the Revolution, protests by judges representing views and privileges of the social classes to which they belonged. Such conflict led the Revolutionaries to take a negative view of judges making law.
During the 19th century, the Napoleonic Code was voluntarily adopted in a number of European and Latin American countries, either in the form of simple translation or with considerable modifications.
I think they went to Idaho.
