Don't be silly. The Roosevelt Corollary does not set the US out as guardian and protector of the Western hemisphere. It does, however, reserve to us (and only us) the right to intervene should any country in the Western Hemisphere act irresponsibly in erroding its own "orderly freedom[s]." Since the most important "orderly freedom" is the right to political self-determination, any American intervention resulting in the overthrow of a democratic regime would necessarily run counter to the goals articulated by Roosevelt in 1904.
I don't know how you could post those two sentences back to back and not notice the contradiction.
I have a reading recommendation for you.
