Israel is a country which is founded, very much, on the premise that there IS a God (that God of the Old Testament). This is true, even if many Israelis today don't even believe it (or don't pay attention to it). To the extent they do or don't, that is their problem and their responsibility (and one they can take up with God themselves).
If Israel has any effective "babysitter," it will be that God (and not the US) who is the force behind it. To the extent the US was "used" for this purpose since the end of WWII, I would opine it's been very much the US which was "priveledged" to do so.
As of Tuesday, I believe, similarly, that the "priveledge" has been withdrawn. To the everlasting shame of the US.
No longer much of an issue--the US now has much bigger problems, in my view, after the events of Tuesday. The way I see it, God (again...presuming he exists at all) folded his arms and, quite deliberately, turned his back on this country this last Tuesday.
So in my view, Israel needn't worry about a sudden waning level of support from the US. It's the US which should worry.
Of course, the rest of the world should worry too (but it won't--human beings never fail to avail themselves of a chance to be stupid).

Now....everything I just said is premised entirely on the fact that the God of the Old Testament exists.
He might not exist too, so I might just be wasting my breath (and a few keystrokes)...and these few electronic bits it takes to put these ideas down on the internet. So peeps like you, stabiz (and subchaser12 too), shouldn't worrry at all if you DON'T believe this God exists.
If you don't believe it, then, of course you are right and I am just a crazy man.
So...let's roll those dice and see! Place your bets!
