You are aware that the Monroe Doctrine also stated that we would stay out of the European sphere of influence? We’re running around Africa, Europe, Ukraine, Georgia, etc.
The way we were able to enforce the Monroe Doctrine, was the fact that we stayed out of that side of the world. We go play in other people’s areas, nobody accepts that we should be given a free hand here.
Remember WWII?
It happened ... it followed WWI and fomented WWII.
Do you see a pattern yet?
