"Isn't the Bible pretty clear in its direction to support Israel?"
Yes, it is very clear. Individual have only two choices. To either bless or curse Israel, nothing in between. Those who curse her, God promises to curse them. Those who Bless her, God promises to bless. The next question is where is your absolute final authority, in God's Holy Bible or in Man.
The longer one puts off putting his faith in God's Holy Word, the better chance they have or their heart's being hardened, their eyes growing dark and never being able to see the truth again. God is slow to anger, but time is running out.
Actually, the next question is, Who/What is "Israel"?
Israel is Jacob, son of Isaac, and his descendents in the Law. It is not a political entity that arrogates to itself the name that belongs to a people. Just because you name something "Israel" doesn't make it so.
