Evolution of Political and Security Relationship between the Republic of Poland and the United States of America in the years 1999–2019

The article discusses the evolution of political and security cooperation between the Republic of Poland and the United States of America in the years 1999–2019. It argues that this relationship has been strengthened over the past several years to an unprecedented level, as reflected by the following: (a) permanent presence of US troops and facilities on the territory of the Republic of Poland; (b) significant reinforcement of energy cooperation that would contribute to the security of the Central and Eastern European (CEE) region; (c) development of a high-level strategic dialogue; and (d) successful widening of the mutual scope of soft security collaboration, including economic, digital and people-to-people aspects. In this article, I try to answer the following questions: what are the reasons of upgrading Poland–US political and security relations? What was the process shaping US– Poland relationship during 1999–2019? What are the priorities for both sides in this cooperation? I suggest that the past 20 years of Polish–American relationship can be divided into three stages: (a) between Poland’s accession to North Atlantic Treaty Organization (NATO) and Russian aggression towards Ukraine (1999–2014); (b) between the NATO Summit in Newport and the swearing in of Donald Trump as President of the United States (2014–2017); and (c) then onwards (2017/2018–).
