You are wrong Bobwaters, but I still love you. If God said 'Any Nation' or "All Nations" then that covers the United states. He knew it all before hand. Psalms 9:17 KJV: The wicked shall be turned into hell, and all the nations that forget God.
God knew at that time even before America was ever founded, that it would be here, and heathen would come along to destroy it. 2 Chronicles 7:14
“If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.”
Matthew 24, and Revelation tells what is going on in our world now.
