Obama’s rise to power undoubtedly represented a profound change with regard to the existent international policies deployed by President George W Bush and his doctrine on Preventive War. From a long-term perspective, this might also mean a turn towards idealism after a long period of predominant realism, which was intensively conducted during the Cold War by means of the Containment Doctrine. Prevalent diplomacy together with restoration of respect for civil rights at the core of all international relations would effectively move idealism-wise. On the contrary, keeping a military-solution scheme within the wars being currently waged by The United States and the consolidation of a global-scope strategic method reinforce a realistic perspective. These are some of the reasons that make President Obama appear to represent a gradual turn in which the idealistic vision mixes, pragmatism involved, with the Containment doctrine, this time not having a global enemy to fight.
