America is reaping decades of murdering unborn children, embracing the vile sin of homosexuality, and generally spitting in the Creator's face concerning all that is holy. Our collapse is not without precedence.
Joshua 23:11-13 is one of many such warnings. Take good heed therefore unto yourselves, that ye love the LORD your God. Else if ye do in any wise go back, and cleave unto the remnant of these nations, even these that remain among you, and shall make marriages with them, and go in unto them, and they to you: Know for a certainty that the LORD your God will no more drive out any of these nations from before you; but they shall be snares and traps unto you, and scourges in your sides, and thorns in your eyes, until ye perish from off this good land which the LORD your God hath given you.
The Old Testament prophets, major and minor, underscore the fulfillment of these warnings.
I am of the opinion that America has for decades spat in God's face and now He's giving our country to our enemies. IMO.
I agree with everything you wrote.
