Abstract

This article examines the US-Cuba relations and the security implication it has on the region in the 21^st century. Both nations hold key positions in the world in their own domains. Cuban transition of ideology has become major security threat to USA and the region. Where Cuba cannot deny its world power neighbour, USA can also not deny the amount of strategic importance its small Island neighbour only 90 miles away from it has. Ever since these stained relations have become more crucial for the rest of Americas. This cold wave between USA and Cuba continued all through the cold war era and even in the post-cold war era, until little breaking of ice happened when Obama assumed the office. Despite efforts from the region and the world, the relations are still far from normal even in the 21^st century. When we combine the geopolitical importance of Cuba with the United States’ national policy of global power, it follows that the control of Cuba was of fundamental strategic significance for the United States in the beginning of the twenty-first century, just as it was in the early 20^th century. This is one of the most important corollaries that can be drawn from studying the history and fundamental documents and doctrines of American foreign policy while studying the security implications of the relations. This served as the foundation for the United States' core strategic objective regarding Cuba Policy of restoring authority over the country through a change in regime. Here in this article factors that involve in US-Cuban relations and their implications for the region have been discussed
