You may be right this nation being destroyed, but it has nothing to do with God being unable to save.
God did not protect Israel and sent her into slavery for ignoring God’s laws. Americans have been mis-educated for so long, they no longer understand that nations can fall without a war. I do not believe God will save a nation that sacrifices its young on the altar to Molech.
Nor will He continue to bless a people who turn their back on Israel. All of history is God’s. Its beginning and its end and all is ordained for His purposes.
