Regarding how the French people might perceive it, opinions on Napoleon are quite divided. Some view him as a visionary leader who brought about significant reforms and modernized France, while others see him as a tyrant responsible for numerous wars and loss of lives. Given this complexity, it's likely that reactions among the French would be mixed. Some might see Trump's quote as a positive nod to Napoleon's legacy, while others might view it critically, especially considering the authoritarian undertones associated with Napoleon's rule.
As for whether Trump was being ironic, it's hard to say definitively without more context. His use of the quote could be seen as an attempt to align himself with strong leadership qualities, or it might be interpreted as a more tongue-in-cheek reference, given the controversial nature of both his and Napoleon's actions.
He who saves his Country does not violate any Law.
