Gulf states shunned Egypt in military operation
Egyptian television presenter and interviewer Ahmed Mansour wrote on his Facebook page the reason for Egypt's negligible role in Operation Determination Storm was due to Egyptian President Abdel Fattah al-Sisi's secret backroom meetings with the governments in opposition to Saudi Arabia and the rest of the Gulf states.
Translation: After the Gulf states realised Sisi’s betrayal and secret meetings with the Houthis, Iranians and Syrians to plot against them, they did not inform Sisi about operation Determination Storm and did not ask him to participate. And when Sisi woke up and found that the Gulf states had taken the matter into their hands with a surprise war to secure their existence and borders and curb Iranian influence, Sisi rushed to declare his support of the operation and willingness to participate. But the Gulf had already sent the message across and taught Egypt a lesson.
