Today, relations between the US and major European powers are still strained, and their hottest points are currently attributed to the “inadequate Trump policy”. It is not so obvious as it seems, because even during the presidency of Obama one could overview the disagreements between the partners. These were covert disagreements, which the parties tried not to show. Now Washington wants to set its own terms, thus demonstrating all the problems the parties have. The main question is how flexible the partners could be in order not only to save the unity, but to show the desire to strengthen NATO alliance and respond to the existing challenges.
