The Eagle with the outstretched wing has always been a symbol of God's household Israel. That is why the US has it as it's symbol. Study the book of Jeremiah and it will tell you about the land of the corn /USA/. Israel is a who not a where. Israelites/Adamites have been in America even before Solomon brought them in around 950 BC. In order to understand Revelations or any of the scripture you have to know who the people's are. The Book of Acts tell who the jews are.
