Those countries were not founded on a Christian world view and Christian principles. So they were never blessed like our nation, who, in its beginning, openly and universally acknowledged its dependence on God for all things.
The difference could not be greater.
God, and specifically a universal general belief in the Lord Jesus Christ is what resulted in our nation being unique and exceptional. That is a fact. Every principle embodied in our Constitution came from the Bible.
Those other nations may be prospering materially, but have never prospered spiritually. I’m referring primarily to the moral and spiritual decay of our nation, not the material.
It's kind of ironic that as we get closer to the edge of the cliff our government and our fellow citizens are trying to tame down our sporting exhibitions rather than making them even more violent in order to mimic the Roman gladiator matches.
Of course there is plenty of simulated violence on TV, in movies, and on the internet but nothing says moral decay like a real live Lion vs. Christian match.
