And the Lord gave unto Israel all the land which he sware to give unto their fathers; and they possessed it, and dwelt therein. Jos 21:43 The Lord fulfilled His promise to Abraham regarding the land.

And the Lord gave them rest round about, according to all that he sware unto their fathers: and there stood not a man of all their enemies before them; the Lord delivered all their enemies into their hand. Jos 21:44 The rest happens only when everything has been accomplished and fulfilled.

There failed not ought of any good thing which the Lord had spoken unto the house of Israel; all came to pass. Jos 21:45 So everything that the Lord had promised to Abraham and to his descendants was fulfilled.     There was nothing else to be fulfilled except the promise of the Messiah that was fulfilled in Christ Jesus.

Since all the promises to Abraham and Israel have now been fulfilled it is clear that the people who project promises being fulfilled by God for the current state of Israel are in error.   

This means that people like Jonathan Kahn who is a Christian clinging to his Hebrew origins and Jewishness is wrong about his 'prophecies'.   He is casting world events in a way to justify Israeli (Zionist) goals of world conquest.   

I am virtually sure that the Beast will be given power by influential Zionist Jews in government, technology and finance.   

Since the Jews consider non-Jews as Goyim (inferior beings) the Beast will be one of their own as he 'receives' power.   He does not take it.   

This prophecy by Christ Jesus is profound and very telling:

I am come in my Father`s name, and you receive me not: if another shall come in his own name, him you will receive. Joh 5:43 What is the Father's name which Jesus came in?     Jesus.      Jesus is the incarnation of His Holy Spirit Father.      This, as usual, is the Holy Spirit speaking through Jesus.     However, in this verse He very plainly speaks to the fact that His Holy Spirit has come to manifest Himself to the world, and His name is Jesus.      Jesus is the Father revealing Himself to us directly.      Jesus is the Truth.      All others come in their own name speculating about and talking about deity,

The Beast will be an amoral secularist who disdains religion in all forms.   He will come in his own name as a man who will save the world through his own human skills.   

The 144,000 from the twelve tribes Rev 7:4 is a pittance (1.6%) as there are 9,000,000 Jews alive right now.
