"
I am a Christian. Does my religion call on me to oppose Israel or not? I am asking you to clarify this for me."
That's a question better answered by people of your own religion (behind the link).
Israel, Palestine and the Middle East

I believe the words behind the following. To change that belief is unthinkable.
Zechariah 14:9
Malachi 3:6
I have not dug through it all yet. But I think he uses St Paul's words in a tortuously selective way. Here are the most relevant Romans 11 versus from the NIV:
28As far as the gospel is concerned, they are enemies on your account; but as far as election is concerned, they are loved on account of the patriarchs, 29for God's gifts and his call are irrevocable.
Verse 29 seems to be rather inconvenient for his conclusions. As far as verse 28, I could not tell what translation he was using, but none of the ones I looked at stated that "they were enemy's of God" like his did.
I might go through it a bit more later, but I think it does not look like his doctrine is well founded in Christian Scripture.
