Beet1e,
I been relatively outspoken on this very BBS about the US relationship with Israel. I'm sure a quick search will turn up more than you want to read.
If it were me, I'd tell them to get back behind their UN designated borders or I'd cut off all aid. After all, taking territory by conquest is what we went after Saddam for in '91 right?
However, if one does that, one has to provide them reasonable assurances that they won't get shelled and rocketed from the Golan Heights, etc, etc, etc.
That means dealing with their neighbors who have sworn, on and off through the last 50 odd years, to eliminate Israel from the map.
So, at the same time you make Israel the offer they can't refuse, you have to make a similar offer to their neighbors and that's where it gets sticky. You have to be extremely ready to "crack heads".
Or, I guess you could tell the Israelis that they have to withdraw and if they later get attacked they have the OK to use their nukes....
But, all in all, there's way too much support for Israel from the US. They don't deserve all of that support, either.
The current "road map" is an example. The PLO said "we accept!" the Israelis said "hey wait a minute! There's a few dozen or hundred changes we want here!".
