God repeatedly ALLOWED a wicked Israel to be conquered by her enemies, taken into captivity and a remnant of the their children to be freed and brought back to His Land after many years.
The cycle was so numerous and Israel so adulterous that God essentially gave her a divorce.
“I gave faithless Israel her certificate of divorce and sent her away because of all her adulteries. Yet I saw that her unfaithful sister Judah had no fear; she also went out and committed adultery” - Jeremiah 3:8
America will suffer the same fate and worse - because America had in her His Holy Spirit among His people which Ancient Israel and Judah DID NOT have access to.
In short, we knew better and it will be more tolerable in the day of Judgment for other nations than ours.
Anyway, that was before the redemptive grace of the Lord Jesus Christ who ushered in the freedom-declaring New Covenant, which is ignored by too many believers (not unlike the freedom-declaring Constitution which is ignored by too many Americans), whereby God has declared, "I remember their sins and inequities no more" (Heb 8:10). You may remember your, others', and America's sins and iniquities. The devil may remember them. But God does not, because they were all judged on the body of Jesus Christ on the cross and God is holy and righteous to not judge the same sins twice.
