Saudi Arabia has been known for its conservative approach in foreign policy in the region over the past decades, but with the imposition of Salman and his son Mohammed bin Salman, this country has adopted an aggressive foreign policy in the region, for example the military invasion of this country with The so-called military alliance to Yemen.
The Yemen's geopolitical, geostrategic and geo-economic positions as well as the aggressive policies of Saudi Arabia and the support of some transatlantic powers, including the United States from Saudi Arabia, and the shift in the balance of power in the region against the Saudi Arabia are the main causes of the military invasion of Yemen, which has had adverse consequences such as the defeat of the Saudi greatness, decreased Saudi soft power in the global public opinion and shattered Bin Salman's position for Saudi Arabia's current sovereignty.
