The author is forgetting Someone rather important. He would be wise to read again the account of Isaiah 37, when an angel of the Lord God put over 185,000 Assyrian troops in one evening.
If America abandons Israel, then it will not be disaster for Israel, but rather curses and destruction for America.
I don't think the angel put them over, he killed them. I have heard people say that Israel does not have a Masada complex. They have a Samson complex. Their Arab neighbors should remember this.
