It almost avoids the issue to answer this and it should really be sufficient to note that my contribution to this thread has not relied on prophecy.
Within the Christian perspective, there is a view of what Israel is now and what Israel is to be. The return of Christ intersects the two. One is not to be confused with the other. Every Christian's hope is the return of Christ and Biblically, the place of return is identified as the Mount of Olives and Christ reigns out of Jerusalem (which is Biblically described as the Lord's inheritance and the seat of Davidic Kingship) with the Kingdom of God spreading outwards to the nations. So, Israel is bound up in the promise of Christ's return. Prior to that return there are a whole series of prophecies concerning Israel which I don't think should be articulated here.
Support for Israel as it is now is not unconditional on every level because Israel, if you'll excuse the Christian language, is without her King. But my view of what Israel will be contrasts what others believe, of course. As I mentioned before, I am used to others mocking Biblical Christianity but the conversation regarding Israel's actions today should remain where it has largely been previously in this thread. I just hope for an increase in quality.
