Considering that God has been thrown out of the public square and our culture while the Faithful have sat on their hands and remained silent…. I do not find any biblical examples of Providence coming to the aid of a people who have gone astray and abandoned their faith and country to the wicked.
Of course God is bigger than our adversaries. But when a nation fails to repent and practices Isaiah 30:9-11 on a national scale, your admonition would rely on the strength of our own political countenance of which I have no confidence.
God did for about 1000 years with Israel.
