Ron Paul does not back the State of Israel, which is exactly what Hezzbola, Islamic Jihad, Hamas, the Iranians, Muslim Brotherhood and the entire Islamic Caliphate want.
As such, Ron Paul has "cursed" Israel.
The modern "State of Israel" is not Israel. The United States can't manipulatively curry the favor of God by financing, arming, saving or otherwise "blessing" the modern, secular, State of Israel.
God will bring the remnant of Israel to repentance in His own way. He does not need our military technology or our debt to do it.
Luke 3
Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham.
Zechariah 4:6
Then he answered and spake unto me, saying, This is the word of the LORD unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the LORD of hosts.
I don't always comprehend Ron Paul's augments and I can't follow his reasoning. If he saw a man being beaten in the street, would he stand by and say "I am opposed to all violence" or would he intervene, perhaps violently, to stop the violence? I don't know. But in the realm of States I have to conclude that the situation is much more complex and we can't reduce our policy to Israel is God's therefore we defend Israel (while we also finance and arm all of Israel's enemies).
At least Ron Paul is consistent. He does not believe in any foreign aid. The leaders of nations everywhere, including Israel and America, are grotesquely corrupt and corrupting and are leading everyone in enmity to God and on a path to rapid destruction.
Psalm 2
1 Why do the heathen rage, and the people imagine a vain thing?
2 The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, saying,
3 Let us break their bands asunder, and cast away their cords from us.
