Sooner more likely than later.
Very soon, Israel could find itself in an indefensible position, with nothing left but to fight on, because surrender is not an option that will be offered to them.
An Obama Presidency offers no moral sanctuary for the Israelis, as by past statements, and Senate votes, he has hardened his heart against any possibility of ever taking up any advocacy for Israel. With the uncertainty facing them, the Israelis would be in a better position if hostilities began BEFORE the US election in November. Then, the US President HAS to make some kind of response, something that shall burden the next Administration with either maintaining support, or withdrawing it altogether, and leaving Israel to its fate.
Can America afford to abandon Israel? What would that say about what America has become?
Whether the US can "afford" to abandon Israel, or not, is moot. The US *will* become like the other "nations" and not only abandon her, but oppose her. One can see this happening in fornt of one's eyes, and it's no longer really deniable, in fact it's laughable to deny it at all.
This was all foretold, long before there even *was* a US, and so, should come as no surprise...
