The study focuses on the international security agenda found within the Euro-Atlantic arena of political and military activities, and on different institutional and organizational levels of various security interests, visible through official transcripts, discussions, and activities of Euro-Atlantic organizations, including the European Union, United States, Poland, and other States of Europe, in view of President Barack Obama’s policies. Authors’ approach towards the subject is analytical, whereas the particular elements, especially the chosen security outlooks examined, are presented in order to present a synthetic view of the elements and generalized evaluation evolving. The spatiotemporal extent of analysis is positioned within the frames of Barack Obama’s presidency. Authors argue that, since the main security agenda and the Euro-Atlantic relations, with its emanation on other regions of the world, centers on the American military leadership, run by the policy and leadership of the United States, the changes of the White House cabinet is determinative for other areas. Yet, the growth of the European Union into the big European entity would also become an important determinant within this time-based outlook and a major factor in the following relations. The appropriate discussion with fact analysis follows. Place of Poland in such a scenario became difficult in a way, that given the political party government of Poland, it would have to take sides, or level the international differences between the USA and the EU, even in a limited capacity of influencing the outcome.
