Couldn't the eagle's wings being removed from the lion just refer to the division that occurred when we (the U.S.) became our own nation?
Well, only that the symbol of the eagle isn't mentioned anymore past that point. And the next time we see Britain- the lion (her symbol today), is when the antichrist's empire is formed. Part bear (Russia), part lion (Britain), part leopard (Germany) and teeth of iron (Italy-Rome).
These will be part of the ten nation empire, but these 4 nations (the heavy hitters) will have most of the power.
