It is interesting how the question of, What happens to the USA? is getting clearer.
There’s a reference of a nation represented by an eagle which raises vocal objection to what is happening against Israel, but I don’t recall where that is. I’ll try to find it.
It may take some time.
Growing up it seemed impossible to me that the USA wouldn't be in charge of everything. Now in a couple generations we've got abortions going on all over with our tax dollars. We have sexual deviants being declared to be normal, healthy, happy adults. We have fewer people going to church on a regular basis. We have fewer marriages and more children born outside of marriage. IOW, we are disappearing as a force for good in the world and falling into a cesspool.
I can’t recall the verse that I was thinking of, however, there is this verse, which MAY indicate involvement of the US.
Revelation 12:14
The woman was given the two wings of a great eagle, so that she might fly to the place prepared for her in the desert, where she would be taken care of for a time, times and half a time, out of the serpent’s reach.
Otherwise, it is conspicuously absent from Bible prophecy and that in itself may be an indicator that the US is not a major player in the end times events, which primarily surround the Middle East.
