There is a religious crisis in Islam which is being willfully ignored by the religious and political leaders. To understand this delima, you must first understand Islamic logic and reasoning. You see, Muhammad gave the end time prophesy that the Jesus of Islam would conquer the world and Jerusalem and give the command to his Muslim followers to kill the rest of the Christians and Jews and, if you are a Muslim and don't believe Muhammad, then you are a hypocrite, will burn in Hell, and most be searched out and killed.
This all means that, if you are a Muslim and try conquering the world or even just Jerusalem without the Jesus of Islam, then you are saying with your actions that you don't believe Muhammad and are, therefore, a hypocrite, will burn in Hell, and must be searched out and killed by other Muslims.
The real delima comes when one also realizes that Muslims are guaranteed salvation for killing or trying to kill non-Muslims in this Jihad against the world BUT, if they are committing hypocrisy by trying to conquer the world without the Jesus of Islam, then they not only don't get guaranteed salvation but get eternal damnation for calling Muhammad a liar with their actions. In other words, when they die in this Jihad, they go to Hell.
This means that the Islamic reason the Muslim Caliphs didn't succeed in conquering the world before the Christian Crusades fought to stop that conquest was because they tried to conquer the world without the Jesus of Islam calling Muhammad a liar and branding themselves as hypocrites. By Muslim logic it means the Caliphs were punished for their blasphemy against Muhammad by their actions. It also means that all the Islamic martyrs who died fighting to conquer the world without the Jesus of Islam did not earn salvation but were slam dunked into Hell forever.
It also means that any and all Muslims who die fighting to conquer the world today without the Jesus of Islam are not getting salvation but, instead, are being sent to Hell by Allah for calling Muhammad a liar with their actions. This is especially true for those trying to conquer Israel and Jerusalem without the Jesus of Islam.
You see, if they succeed in conquering the world without the Jesus of Islam, then Muhammad was wrong and a liar. If Muhammad is wrong, then Islam is a lie and they will all go to Hell for believing it. Therefore, since the Muslims believe that Muhammad is not wrong and a liar, then they can't possibly conquer the world, Israel, and Jerusalem without the Jesus of Islam and any attempt to do so MUST end in failure with the Muslims who called Muhammad a liar by trying to conquer the world without the Jesus of Islam being hypocrites and going to Hell.
This creates the delima that, if they continue to try to conquer the world and succeed without the Jesus of Islam, then they will prove Islam to be a lie and must then reject it. On the other hand, if Islam is true, then they can't succeed with their current effort to conquer the world, must fail, and should stop trying until the Jesus of Islam arrives.
Therefore, according to Islamic logic, if they gather their forces against Israel and lose the battle as predicted in Ezekiel 38 & 39, it will be because they sinned in calling Muhammad a liar and everyone who was killed in the battle is a hypocrite and will go to Hell. If they continue with their current efforts to conquer the world without the Jesus of Islam, then they are in a lose-lose position. Even if they succeed in conquering the world, they lose because they prove Islam to be a lie.
Therefore, according to Islamic logic, they must stop the fighting and wait for the coming of the Jesus of Islam or be branded as hypocrites, be searched out and killed, and risk eternal damnation. They have no other choice BUT the current religious and political leaders' lust for power is so great that they are willfully ignoring this delima and keeping it from their Muslim follows leading all of them to Islamic Hell while promising salvation.
