I don’t think it will be the “fall of Rome”, just some massacre somewhere. A very visible defeat that even the MSM can’t spin away.
The problem is that our leaders will still cling to PC BS regardless. Kind of like after the financial crisis, where they still wanted lenders to lend to people in the subprime market. The necessity of not being racist, sexist, or homophobic will trump all.
I think it will be international.
I think it will be Revelation 18.
But, that’s just me.
