In this article, the attempt is made to study the causes of US policy towards the North Atlantic Alliance under the administration of the 45th US president. American policy is analysed through the prism of renegotiation/new bargain concepts and from the standpoint of US domestic political considerations. This article also provides an analysis of European policy alternatives in response to the current US policy towards NATO and dilemmas inherent to each alternative. The article also features a brief analysis of why NATO still corresponds to US national interests to make a case that a policy of undermining this Alliance would run counter to American long-term strategic considerations
