As a country, we can afford to bear a certain number of dumbasses and evil people and be fine. We’ve always had them, even when the country was founded.
However, when enough people have adopted unwise values, the accumulated weight of our dumbassery ensures our destruction eventually.
God told Israel to repent as a nation, so we, as a nation, have that same responsibility whether or not we can convince enough people to repent as individuals to avoid destruction.
I thought about that when I first read your comment. But, first, America isn't Israel. We are a wide mixture of mostly pagan peoples from around the world.
On the other hand, Israel (by virtue of its Patriarchs) had a covenant with God.
Second, God knew that Israel would not be obedient or repent. Hence His continual exasperation with her.
As an aside, I have always been curious as to why omniscient God would be exasperated when He already knew Israel wouldn't repent. I guess that just shows how He respects the freewill that He has given humans...and how much He loves us despite our hardheadedness.
