Modern-day Israel is the fulfillment of prophesy. To oppose Israel is to oppose the will of God, who has not abandoned "the Chosen People".
"I say then: Hath God cast away his people? God forbid. For I also am an Israelite of the seed of Abraham, of the tribe of Benjamin. God hath not cast away his people, which he foreknew.
... For I would not have you ignorant, brethren, of this mystery, (lest you should be wise in your own conceits), that blindness in part has happened in Israel, until the fulness of the Gentiles should come in." - Romans 11:1-25
