Bin Salman's defeat in the Yemen war; The result of incorrect calculations Dr. Dariush Darvishi, an expert on Saudi issues, in a conversation with Nasim Online: Perhaps the main reasons for the failure and lack of success of Saudi Arabia in the Yemen war were that Bin Salman did not have the correct calculations. Experienced people in Saudi Arabia were against this work, but a newly appointed person who was interested in power, started this war based on an illusion that was ready for him. He did not think at all that in the very difficult and special land of Yemen with that special culture and spirit, how he could advance and reach his destination with air attacks or air superiority that he had.
