Marc, I have been in Jerusalem for almost four years, and you are right.
One can read what Mark Twain said about Palenstine when he was there in 1867. It was a wasteland then.
Yes, some Christian writers were from there, but that was mainly in the first few centuries ad.
Jews have always been there , but not in Jerusalem for awhile after the Barchova revolt.
The political situation is very complex.
The crusaders murdered, Jews, Christians, and Muslims. The city of Jerusalem was a waste for many years there after.
To boycott Israel would hurt Israel and the Arabs, who call themselves Palestinians.
BTW, before 1948 the Jerusalem Post was called the Palestinian Post.
