The big difference between France and the USA is that the French people usually either passively or actively support them and do not see any problem with what they are doing and would much rather look at the evil Americans. It's not even a political issue, it's almost seen as a divine right.
That's literally one of the main reason macron has been popular: his wannabe bonapartist "great France" mindset (and even those who dislike him don't usually criticize him on that front) that involves crushing the ennemies of France, and a whole lot of illusions of grandeur.
It's also a country where the literal neonazi FN still gets 40% of the votes, but people still laugh about dumb Americans because they voted for trump. Keep in mind, the only reason we don't see more french droning in Africa is because they lack the ability to do so.
And I'm not American or French, but I've had a lot of first hand experience with the damage France is causing in Africa and I'm very familiar with French culture. Yet I'm almost always amazed by the extent of French grandstanding online.
