Depending on if you think America is an extension of Europe (or Babylon) then I think there was a passage stating for His people to come out of her before it was too late.
"Go forth from Babylon! Flee from the Chaldees!" (Isaiah 48:20).
"Depart! Depart! Go out from there, touch no unclean thing; go out from the midst of her, be clean, you who bear the vessels of the LORD" (Isaiah 52:11).
"Move from the midst of Babylon, Go out of the land of the Chaldeans" (Jeremiah 50:

.
"Flee from the midst of Babylon, And every one save his life! Do not be cut off in her iniquity, For this is the time of the Lord's vengeance; He shall recompense her" (Jeremiah 51:6).
"We would have healed Babylon, But she is not healed. Forsake her, and let us go everyone to his own country" (Jeremiah 51:9).
"My people, go out of the midst of her! And let everyone deliver himself from the fierce anger of the Lord" (Jeremiah 51:45).
"Up, Zion! Escape, you who dwell with the daughter of Babylon" (Zechariah 2:7).
"Come out of her, my people, lest you share in her sins, and lest you receive of her plagues" (Revelation 18:4).
Often I wonder if the correct approach is to move. [Not saying I'm punking out or anything.] But I get the understanding that God deals with holiness, which is separating oneself from sin. And numerous instances God tells people to flee. I think even in some places Jesus "fleed." Not out of fear really, but out of obedience to God. And the question is, considering everything, what does God command.
Would God say stay and take up a sword to defend a country, attachment, oath? That sounds harsh, because it's first instinct, but is that ever the case in the Bible? (No rhetoric, I really could use some secondary insight) Or is God telling His people to flee?
Something also that struck me recently was how Prince Charles coat of arms looks like the Beast described in the Bible. Is this mystery Babylon? If so, where does one go to get out? What if someone can't?
Very deep questions.
Oh and I agree that God wouldn't want his people under tyranny, but there have been times they have been. And I also agree that many churches are gone in one way or another, heresy, apostasy, you name it. Difficult to discern sometimes.
And then there is the question, if Satan is the ruler of this world, and we submit to rulers of the world, are we submitting to the Beast? Is that worshiping the Beast? If rulers are ordained by God, then can Satan's minions be ordained by God?
