Hmmmm, perhaps you could look through the Monroe Doctrine and find where it states this argument. The Monroe Doctrine was orginally intended to protect the Western Hemisphere from Europe, not the states from themselves
Although it won't happen, Chavez and Castro should be next on our list.
LOL!! The neocon line now on in our own hemisphere. How fantastic. Tell me, when we get rid of these dictators, who are we going to put in next, and how long before they turn against the hand that feeds them, as Castro did?
