In 1858 Italian Felice Orsini attempted to kill Napoleon III,according to him a republican revolution would break out that would expand to other countries including Italy.What would happen if he succeeds in killing emperor?I think republican revolution would not happen,in fact this would lead to suppression of republicans in France. IOTL many thought of a British involvement since the bombs were made in the UK but Napoleon III did not want to elaborate,what would the new emperor Napoleon IV do instead?
