Christians have no greater ally than the Jewish state,
I don’t know where the “gaffe” is in that statement.
He should have said “the Jewish people” and he should have clarified, the Practicing Jewish people.
What’s wrong with the Jewish state per se, in that case?
Or he could have simply told the truth and said France.
If you think in terms of world religions, Judaism and Christianity are more closely related than either of them is to any other religion.
