I know about the hostility of the Muslim Brotherhood and the kingdoms of the Arabian Gulf. But here we are talking about the genocide of an entire nation! History will judge them as traitors in the future. Accordingly, history judge us in the same way since we did not help the Greek Cypriots in 1974 and carried out a pogrom through EOKA B' against the Turkish Cypriots in Cyprus. If they want the kingdoms of the Arabian Gulf to be branded with such shame in their history then what can I say. The geopolitical chessboard, the power, the financial deals of billions are good, but the historical imprint of a state over the centuries is more important than money. Israel must know history and realize that no state or empire in mankind has ever conquered another state causing total annihilation of the native population or oppressing it forever! Not even the British in North America were able to completely wipe out the Indian population, nor did the Spanish or the Portuguese. There are still native Indians with large population growth and economic/political power in the US. If Israel thinks that it will be able to completely conquer these territories, it is probably dreaming of things that cannot be done practically, nor can they be morally accepted by any state, not even by the USA. The Palestinians will stay there no matter how much some people don't want it, it's just that the hatred against the Jews will grow so much that when Israel becomes in a few years a minor geopolitical ally of the USA, due to a shift of the axis to the China Sea and Africa, then the Palestinians will commit atrocities 10 times more brutal than those we see today in the Gaza Strip and the West Bank. Hate will breed hate and this is something that will endanger the very existence of the state of Israel and the Jews who live there. It is in Israel's interest to create two states of Israel and Palestine or one state together.As much as I wish this to happen, you simply could not bank any hope whatsoever with Arab states. For one Arab states like Saudi, Egypt and UAE actually HATES Hamas more than Israel, because Hamas is one of the remaining active militant wings of the Muslim Brotherhood, and Gulf monarchs HATED Muslim brotherhood because they saw it as a threat to their throne.
So ignore the rhetorics, secretly behind the scenes they are very likely coordinating with Israel on how to destroy Gaza. The only MENA country with legit anti-Israeli attitude atm is Algeria and that's it.
So the normal conduct of alliance is out of the question, none of these Gulf Arabs will raise weapons unless of course there's an event that forces them to. Such as this which I wrote a few weeks back. Just like in WW1, small localized conflicts could expand uncontrollably.
