I will agree that the Monroe Doctrine in the end did us more harm than good.
We ended up with 75% of the hemisphere run by 3rd world style governments, and nations with no core concept of liberty because they were mostly formed by people’s that immediately put dictators, and strong-men into top office. Even without the Europeans, most of them turned into basket cases.
The only places that escaped that fate for the most part are the places that are either English-speaking or are still European territories. How ironic.
Like a bunch of Spanish, French, Portugese, and Dutch colonies in our hemisphere would have led to prosperity and development south of the border
Like it did in Africa
