Saudis are way more powerful and influential than Egypt, they spent 100 billion+ of petrodollars to spread wahhabism around the world, they fund media, schools, maddrassas, masjids, tv channels, social media, Quran competitions, literature etc, just about everything to spread their sectarian ideology, these zombie followers then follow Saudi directions and are loyal towards them, they influence muslims, politicians and promote pro Saudi directive. For example currently they quote Islamic literature and claim Usa/Israel v Iran is 2 evils killing each other and sometimes Allah almighty makes 2 evil fight each other, in order to destroy them (in another words follow Zionist agenda), regarding Palestinians their muftis say Palestinians should leave Gaza for their own safety (indirectly supporting the zionist agenda), they claim Palestinians are suffering because they commit shirk (typical khwarij ideology).
Saudis also maintain close strategic relationship with the Usa/EU, and secretly with Israel, they invest 100s of billions in to the western world, maintain close partnerships. Do people believe Saudis will sacrifice this for Palestinians or Iran? Muslims are unfortunately (I'll use a decent word) naive people. But these are the signs of the end of times, deception, confusion, propaganda leads a person on the wrong path, people follow foolish people who beautify their speech but its all a trick, they select these people to come on tv youtube to brainwash people.
Egypt on the other hand fought 3x wars with Israel but realised they cannot win, Usa backs Israel, they then submitted to their dominance, no doubt Egypt opposes Islamist MB groups, its because of internal Egypt situation, whilst they allow wahabism due to Saudi relations. So Egypt is a smaller power compared to the Saudis, the same way Emirates are smaller power compared to Saudis. Saudi is number one Usa/Zionist ally.
