That was addressed to Israel only.
Concur; America is a failing White Anglo Saxon Protestant experiment, where a couple of generations undid the foundation of the nation. It is closer to Babylon now than Israel. Rather than pray for mercy on America, we should pray for judgment, that the righteous not be consumed with the wicked. He sheweth his word unto Jacob, his statutes and his judgments unto Israel. He hath not dealt so with any nation: and as for his judgments, they have not known them. Praise ye the Lord. Hear this word that the Lord hath spoken against you, O children of Israel, against the whole family which I brought up from the land of Egypt, saying, You only have I known of all the families of the earth: therefore I will punish you for all your iniquities.
