Repent and be forgiven! Believe and be saved!
We keep trying to fight back, to take back some ground, but end-time prophecy won't be stopped. God will honor our efforts as long as they're in His perfect will, but those efforts will achieve only so much before we're taken out of the way and the full force of evil is allowed to be unleashed worldwide.
When this happens, the United States will fall. It will be taken out of the picture. Just as Jesus will rescue His bride from what's to come, He will also bring judgment upon this nation, once His bride has been removed from it. I'm sure there are many theories out there as to why the United States isn't included in biblical prophecy just as there are a myriad of theories of how the United States is going to meet it's fate.
