What couldve happened if Napoleon kept American lands for France?

If Napoleon had retained control of American territories, it could have significantly altered the geopolitical landscape of North America. France might have expanded its influence and possibly established a stronger colonial presence, leading to conflicts with both the United States and neighboring British colonies. This could have delayed or prevented American westward expansion and the Manifest Destiny ideology, resulting in a different trajectory for U.S. territorial growth and relations with European powers. Additionally, the dynamics of trade and resources in the region would likely have shifted, potentially affecting the economic development of both the U.S. and France.
