You seem to believe this has never happened? If Rome could fall don't bet that America can't fall. All it needs is the power grid to fail for more than a few days. Three days and there's no food in the stores, and no banks to process transactions.
Rome didn't fall because of no food in the stores and banks failing. But what the hell.......Mooochelle said we are all to fat anyway, so maybe not having food for a while is a solution.
If you don't want the power grid to fail, don't buy an electric car that the Democrats are constantly trying to push us to.
Problem solved.
