Always interesting to see what the latest prophecy buzz is, however, Biblical prophecy is always Jerusalem-centric and focused on Israel and surrounding nations. The USA doesn’t figure prominently in prophecy, except perhaps as a minor player. The Bible is about God’s people Israel, not Americans and the USA.
At some point God’s judgement will affect the entire world, and America is no doubt coming under judgement for rebellion against God (suffering the natural consequences of choosing arrogance and depravity over humility and moral behavior). But tailoring prophecy to be all about the United States is stretching things quite a bit.
If you took even a cursory glance at the September 23rd astronomical events you would know that they are all based in Jerusalem. The eclipse is to lift the eyes of the world to the sky. An omen. Pay attention people, something is about to happen.
