America may be a diminishing nation but anyone who thinks that that is THE problem for events to come about has not been reading Bible Prophecy!

All, and that's all nation's that's all people have fallen short of the glory of God!
And certain event's that God fordained will come about.
It's not just about us.
But of course the character and beliefs and actions of the citizens of one's nation will be the factor in the fall decline or the prosperity of that nation!
