America was supposed to be the "new Israel" & up to a certain point it was. God's hand over that nation was clearly seen by the countless blessings it received from Him.
Up until a few years ago it remained the sole world super-power. Economically, scientifically, army wise, natural-resource wise, etc... At the time of the founding fathers, non-believers were scarcer than ivory-billed woodpeckers.
Since then it has slowly but surely been declining as it further moved away from Yehovah.
