Abstract
The aim of the article is an analysis of the transatlantic bargain between the United States and Europe in a historical perspective since the establishment of NATO in 1949 till the Russian aggression against Ukraine in 2022. NATO is described as a transatlantic bargain meaning that the United States commits itself to remain involved in European security arrangements, and Europe contributes significantly to a system of collective defence. The transatlantic bargain remained a crucial foundation for the partnership between the United States and Europe during the Cold War when the Soviet Union constituted a tangible threat. After the Cold War, there have been many problems in the transatlantic bargain, but Russia’s attack on Ukraine in 2022 highlighted the importance of NATO as a defence alliance. However, the transatlantic bargain may be challenged by the transactional and unilateral approach of President Donald Trump, who returned to power in 2025.
