Be careful with your Replacement Theology.
It’s from the pit of hell.
Modern Israel (those who will look upon their Savior Jesus - see Zechariah 12:10) will be refined as gold in the fire and saved.
Notwithstanding that Jews who reject Christ as the Messiah and the Son of God are just as condemned as anyone else who likewise rejects Him: is or is not the modern nation-state of Israel a manmade creation?
Maybe it’s old, you still can’t wipe away the fact that for decades “Christian” Russia murdered their own babies at a rate that would make the ancient worshippers of Ba’al blush.
Given that the USSR was an officially atheistic state as a matter of state policy, claiming that Russia's high abortion rate during those decades was somehow a reflection of its Orthodox heritage is a very uncharitable take.
