美國對於海地政治發展的影響甚遠，但是海地的民主並非自己發展出來，而是美國強行干涉其內政灌輸的，2006年雖然舉行了總統大選，普雷瓦總統借助聯合國維和部隊的力量稍微穩定局勢，海地還是很有可能在陷入混亂武裝份子反抗，最後又會造成內部局勢的動盪，由此可見美國在海地輸出的民主與干涉，與其社會現實差距甚遠強烈矛盾，因此可見美國的經驗革命不能輸出，每個國家必須針對其狀況發展。 Haiti''s colonial legacy is blame for much of its structural instability: slavery, a corrupt and repressive mulatto elite that ruled over the black population from independence in 1804 until the US occupation (1915-1934). When instability made foreign companies lose interest in Haiti’s cheap labor it suffered economic bankruptcy. Then the Duvalier family dictatorship rule Haiti 29 years. Since Jean-Claude Duvalier was pushed out in 1986, elections have been violent and have rarely resolved any of country’s pressing problems. When Jean-Bertrand Aristide, first came to power in 1990 at the head of the Lavalas grassroots movement, he only lasted a few months before the military kicked him out. Reinstated thanks to US intervention in 1994, he was only allowed to complete what had been his original term in office. At the same time, the UN starts Peace Keeping Operations in Haiti.
By the political crisis happened again in 2004, especially in a country where the U.S. has traditionally intervened. That shows the U.S. intervenes defeat. Therefore the U.S. experiences cannot output, each country must aim at own condition development. After the political crisis, the UN Security Council sent Minustah. The stabilizing has succeeded in organising the elections but has not been able to stop the increase in internal instability, violence, the growth of armed groups or the economic crisis.
