I mean if you think about it, Jews believe that in their Greater Israel everyone else will be their slaves, they are the master race and technically they are now at least in Middle east and America. In a perfect Jew ruled world its not like the Arabs are vanish or Christians are all gone, its that they "Gentiles" are there to serve their Jewish Masters, there are literally speeches of Rabbi's saying just that, now with War and beat down of Muslims in their own country they have effectively presented their dominance, and the Genocide in the Palestine shows just that, never in the history Arabs sits quite and take this abuse, heck they even fight the Ottomans, but if you notice that since the last war between the Arabs-Israel, they (Jews) have checkmate the Arabs/Muslims completely, and now all the territory they want within the Greater Israel is under their rule and dominance, they don't have to physically there, because they will avoid the deaths of Jews by Bedouins but in fact they stay in their Stronghold (Israel) while effectively maintain their dominance in that entire region, that is what Greater Israel was/is/will be, now what is left is that rebuild of the Temple, Also remember that In End Times Prophet said that Muslims will be in Large numbers but will be totally useless, now once you capitulate the leaders of Muslim world they will take care of the common civilians by force, All these Kingdoms are basically under total occupation they just don't know it, just like America is under their total control Americans starting to realize it but can't do shit because their leaders will use force like Police/National guard on their own for Israel.
