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...

You need to become the “spell checker’
Unless Israel limits itself to SLBMs, it will have to fly over Iraqi territory. If that happens, the Iranians will attack American forces. If that happens, we will finish the job that the Israelis started. Besides the spike in oil prices, if this scenario happens, I would expect cells in the US to be activated also.
