And God says come out of her my people...
Where the heck could we go?
Firstly, God has commanded the rest of the Christian world to abandon America's culture, politics and ideology and not to be influenced by such products of the U.S. media.
Secondly, God has also commanded America's Christians to forsake all the aforementioned, which are effectively sinful rebellion against him.
Thirdly, Isaiah 24:1 says that the Great Tribulation would destroy the entire earth, which means that every country would be affected, not just America.
Fourthly, Isaiah 24:10, 12 have suggested that the devastation wouldn't be uniform throughout the entire earth, since on the one hand, "there will be cities that lie empty and people will lock themselves in their houses", but on the other hand, "all the buildings will be knocked down", which means that V10 and V12 are mutually
exclusive; but it only makes sense if we assumed that some cities would be more devastated than others, or perhaps some parts of the city are more devastated.
V10 seems to suggest that the devastation would only affect human life leaving much of the infrastructure intact (Since entire cities would lie empty), but V12 seems to suggest that the extent of devastation would affect both humans and the infrastructure (Since all the buildings will be knocked down and all the city gates will be smashed).
Now, since the devastation wouldn't be uniform throughout the entire earth this is consistent with the theory that "America would still be more devastated than any other country".
Such a theory is consistent with the idea that "America-Babylon would eventually fall as the world's preeminent superpower"; and the fall/destruction of Babylon is mentioned in Revelation 17 & 18.
Lastly, Isaiah 24:5-6 says that "God will curse the entire earth and punish its people, since they have broken the everlasting covenant" - Which is also called the new covenant of Christ = Luke 10:27-28, John 11:25-26 and Romans 10:9 - but presumably, America would still be more devastated than the rest of the world; which means that the U.S. would probably suffer more carnage, death and destruction than the rest of the world.
Assuming this is true, it means that there would be fewer American survivors than any other country, since those "few" people who survive the Tribulation are mentioned in V6, but Revelation 7:9 is constant reminder that those few survivors are still a "multitude which cannot be counted" and they represent "Every
nation and tribe and people and tongue".
For the Destruction of Babylon to be meaningful at all (Revelation 17 & 18), the Great Tribulation would need to affect America more than any other country - Since the entire earth would be more or less destroyed by God's Judgement in accordance with Isaiah 24:1.
For Babylon to lose its position as the world's preeminent superpower (Revelation 18), and to be more devastated than the rest of the world, it would require the extent of America's carnage, death and destruction to surpass the rest of the world.
[That the extent of America's carnage, death and destruction would surpass any other nation in Christendom, it means that there would need to be more Americans who "break the everlasting covenant" (Isaiah 24:5), and conversely, there would also be fewer Americans who accepted the new covenant of Christ.]
Hence, there would have to be fewer Americans who survived the Tribulation by comparison with any other Christian nation, which are among those "very few" survivors briefly mentioned in Isaiah 24:6.
For lack of numbers, the remnants of America would cease to be a superpower in the new heaven and earth and New Jerusalem - Since the few Americans left would be vastly outnumbered by every other nation in the Western hemisphere.
Perhaps, America would disappear altogether as a nation state, since the few Americans left may well be assimilated by other Christian nations in the Western hemisphere.
Whether or not they disappear altogether would depend on the sheer numbers who survived the Tribulation.
