The isolation of Qatar by its Gulf Cooperation Council members and Egypt emerged just days after Trump's visit to Riyadh, during which he has a sudden close relationship with Saudi Arabia. Thus, this study attempts to investigate the potential impact of Donald Trump's nascent foreign policy towards the Gulf crisis of 2017. It aims to analyze the roots of the GCC crisis, and focus on the outrages and the real damage that have defined Trump's approach to foreign policy towards Qatar. Therefore, a qualitative method was adopted, and all the data collected are analyzed using a descriptive and analytical approach. At last, this research shows that no matter the surreptitious motives that are declared about Qatar's blockade, Trump has been the crisis center of gravity from the beginning of the actions of the blockading countries. Hence, Trump's lack of coherent policy in the Middle East comes with real costs and has pushed the region further away from strategic equilibrium and toward greater state fragmentation and conflict between Gulf States.
