Excerpt that best represents the doctrine:
“We owe it, therefore, to candor and to the amicable relations existing between the United States and those powers to declare that we should consider any attempt on their part to extend their system to any portion of this hemisphere as dangerous to our peace and safety.”
This sentence best represents what President Monroe was trying to achieve in the speech because Monroe was cautioning European nations about their foreign policy towards the US. Monroe in 1823 warned European nations in a message delivered to Congress that they needed to stop trying to colonize land and interfere with individual states in the United States and if they didn’t it would be viewed as an act of aggression requiring US intervention. He also went on to say that the United States would not mettle in internal concerns of European countries either. President Monroe also made reference to South America explaining that the southern hemisphere needed to develop on its own without European interference.
