The Assyria of old was destroyed by Babylon, the future Syrian is destroyed by God.
I have another Scripture. Mic 5:4-7 NIV
4 He (Messiah) will stand and shepherd his flock in the strength of the LORD, in the majesty of the name of the LORD his God. And they (Israel) will live securely, for then his greatness will reach to the ends of the earth. 5 And he will be their peace.
Jacob’s trouble before the Millennium:
5 When the Assyrian invades our land and marches through our fortresses, (after 3.5 years) we (God and Messiah) will raise against him seven shepherds, even eight leaders of men. 6 They will rule the land of Assyria with the sword, the land of Nimrod with drawn sword. (Nimrod is synonymous with Assyria) He will deliver us from the Assyrian when he invades our land and marches into our border.
7 The remnant of Jacob will be in the midst of many peoples like dew from the LORD, like showers on the grass, which do not wait for man or linger for mankind.
