The Egyptian airforce is by far the most capable in Africa, endf is in the middle of a civil war and might lose power, what can they do? Most world powers would support Egypt or stay neutral. I mean trump supported Egypt destroying the dam. Biden probably doesn’t but he will be neutral. They 100 % have the capabilities to destroy it if they want to. The effects of destroying the dam at this early stage won’t be catastrophic, the borderlands of Ethiopia and Sudan will be affected however only 5 billion cubic meters of water has been stored, its not that much flooding. This is the best time for Egypt to strike the GERD.
