There is not a single Islamic country in the world that would be allowed to possess nuclear weapons. Pakistan is an extreme exception and an incredible mistake by the Western powers. That is extremely good luck for Pakistan. Fate has it that Pakistan would become a nuclear power.
Well, you are right about that and we have seen this in the Arab world directly (Libya, Syria, Iraq) but that is where you have to play your cards cleverly (don't be as stupid as the Iranians as an example) and make sacrifices.
North Korea did it as well and unlike what many "experts" claim, it did not occur with the blessing of next door China nor Russia. They would have preferred a North Korea that they could fully control.
Nothing. Most non-Western alliances are gestures apart from a handful.
True but even the Western alliances so far have not been fully tested. Would the West and the US really start a potential World War 3 for the sake of say tiny Estonia or Latvia if the Russians invaded or attacked? Not so sure about that one.
In the case of KSA, I am pretty sure that you would have millions of Muslims from across the world willing to defend Makkah and Madinah from say a potential Israeli or US invasion or what not. Regardless of regimes in power.
The alliance is a bluff.
Israel often says the next is Turkey.
So, if war breaks out between Israel and Turkey.
What will Pakistan and Egypt do besides gesture?
Turkiye is a NATO member state. Turkiye was the first country in the Muslim world to recognize Israel and one of the first in the world. They have had diplomatic ties for 70 years. Until 15-20 years ago they had really close military ties. Israel played a role in Turkiye's military industry growth early on in the process.
There is no chance of them going to war with each other any time soon with all due respect.
Unless, in some alternative universe, a future Turkish leader copies the Iranian regime approach of trying to prop up proxy groups next to Israel in order to gain influence.
Of course Israel is against any emerging, strong or stable state in the region. That is self-evident. However they will use the US and others to weaken those countries indirectly first through economic warfare, sanctions, bad press etc.
We have seen in Gaza that no Muslim regime (or non-Muslim regime for that matter) is willing to risk itself by attacking Israel (USA) directly. Hence the tragic fate of Gaza.
Egypt is the only country with a direct land border with Gaza that is not called Israel. You saw what that did. Answer. Nothing.
