The right of the United States to involve itself in Latin American affairs whenever necessary

Explanation:

The Roosevelt Corollary (1904) was a United State policy in which the American government declared itself with the right to act as international police in the conflicts between European countries and the Western Hemisphere (Latin American countries). This meant that if a European country pressed their claims directly to the countries of the Western Hemisphere (such as large debts and civil unrest) the U.S. would intervene.

The Corollary put a limit to European abuses toward Latin America, it displayed how the United States would take a more aggressive role in the world and it established the U.S.'s right to involve itself in Latin American affairs whenever necessary.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
