God will bless America as long as.

Lands are given by God. Aboriginal tribes and people can only live for so long in a geographical place until they begin to trample on God's principles. So the indigenous that reside in a particular place weren't cast out for their godly principles but their way of living which displeased the Lord. History stands by this claim. So United States of America despite their sins always have stood on godly principles, as the founding fathers created as a beacon of hope. That is why many people even today, fleas from their homeland to make this place their home. However, as the past would attest, if United States begins to dive deeper into sin and remove the landmarks of their founding fathers and gear toward a total Anti God agenda and movements, it will take no preference as a world nation, but as God has been consistent with previous nations, will remove and place another inhabitants in its place.
