Because the US isn't!
Most nations aren't explicitly mentioned, only a few. That doesn't mean the US is in the same aggregate as those that aren't mentioned, except in the very final analysis, "Israel & the Nations."
What "nation" is the US?
Abraham-Isaac-Jacob is the "nation" of Israel (Jews).
Abraham-Ishmael is the "nation" of Islam (Muslims).
Now consider Abraham-Isaac-Esau, TWIN of Jacob....What "nation" considers itself grafted onto Israel? What "nation" has a TWIN religious text of Israel? The answer is Christianity (Christians).
Look at the Untied States - forever trying to destroy Israel through the "peace process" and trying to establish the 57th (remember Osatan's 57 states Freudian slip?) Muslim terror state of "palestine."
And now look, the US is waging war in Syria (bordering Israel) and the Russians and Turks have joined. With all The US's troubles, many and major, they are warring in Syria. Isn't there a prophesy about Damascus or something?
The physical Christian nations of the world are the USA and the EU. You can't have ESAU without both USA & EU. That's not a coincidence.
True. I was being logical, maybe too logical. Also, as Lera has somewhat said, we're important because we're the evangelical heart of the world, but that is less and less true as the message spreads outward. When the pilgrims left England, they left empty pomp and ritual behind and brought a purer form of worship. (Of course the Catholic immigrants brought all the ritual back again.)
So we are important in that way. Some of it remains to be seen, especially in the very near future. Maybe JD can talk about some of this sometime.
Yeshayah 17 (Isaiah)
1 The massa (burden) of Damascus. Hinei, Damascus is taken away from being a city, and it shall be a heap of ruins. 2 The cities of Aroer are deserted; they shall be for adarim (flocks), which shall lie down, and none shall make them afraid.
3 The fortified city also shall cease from Ephrayim, and the mamlechah from Damascus, and the remnant of Aram they shall be like the kavod Bnei Yisroel, saith Hashem Tzva’os. 4 And in that day it shall come to pass, that the kavod Ya’akov shall fade, and the fatness of his basar shall waste away.
5 And it shall be as when the katzir (reaper, harvester) gathereth the standing grain, and reapeth the heads of grain with his zero’a; and it shall be as when one gleans heads of grain in the Emek Rephaim.
Aram = "exalted"
Armenian
American
At one time Syria was the 'exalted' nation de jour but the King James translators decided to translate Aram as Syria throughout the entire Bible, oops. Mistake
Now as Ezekiel (post #7) pointed out Ephraim means 'double ash heap' read into that what you like. And the prophesy over Ephraim
Genesis 48:17 Now when Joseph saw that his father laid his right hand on the head of Ephraim, it displeased him; so he took hold of his father’s hand to remove it from Ephraim’s head to Manasseh’s head. 18 And Joseph said to his father, “Not so, my father, for this one is the firstborn; put your right hand on his head.”
19 But his father refused and said, “I know, my son, I know. He also shall become a people, and he also shall be great; but truly his younger brother shall be greater than he, and his descendants shall become a multitude of nations.”
And Ephraim camped to the 'west'
Numbers 2:18 “On the west side shall be the standard of the forces with Ephraim according to their armies, and the leader of the children of Ephraim shall be Elishama the son of Ammihud.”
So don't get excited about the end of Damascus because it means the end of Aram (America) as well.
As always there's lot's more...
