What war are you on about. The Roman invasion of Palestine in 63BC is the only thing I loosely could have referred to with it being the catalyst for the final removal of the Jews from Palestine.
I presumed that your initial remark referred to the creation of the modern state of Israel after WW2. Don`t bring the Romans into it because you are starting to sound like Brian!Probably because it was their land in the first place which they were thrown off by the Israelis.
