According to the description that the chapter gives and the moral decline that we see happening in this country,
the United States seems to be Babylon.
Actually, the verse says,
"And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues."
This indicates that the people who are partakers of her sins will receive her plagues.
But the people who aren't partakers of her sins will receive God's protection, as did the Israelites during the time of Moses when God brought down the plagues on Egypt.
Where does the United States get this stuff?
"The merchandise of gold, and silver, and precious stones, and of pearls, and fine linen, and purple, and silk, and scarlet, and all thine wood, and all manner vessels of ivory, and all manner vessels of most precious wood, and of brass, and iron, and marble, And cinnamon, and odours, and ointments, and frankincense, and wine, and oil, and fine flour, and wheat, and beasts, and sheep, and horses, and chariots, and slaves, and souls of men. (Rev 18:12-13 KJV)
