Israel, if backed into a corner in which they are relatively assured Barack HUSSEIN Obama will desert them (even work against them), has the Nuclear delivery capacity to turn every major Muslim city anywhere near them into GLASS. Be assured of that.
So does Pakistan. That's not exactly a nation friendly to Israel and they can be bought with relative ease. A nuclear strike from Israel would prompt retaliation and escalation into a global conflict. Iran would love this. Bet Russia would jump in.
Is Isreal's nuclear capability enough to disuade escalation? Islamic nations have no qualms with sacrificing their own for Allah. It's the reason only the preverbial adults should have nuclear weapons. They would use the judiciously. But it would not be justified under any circumstances in the global media regardless of whether it was truly a "last resort" for the survival of their nation. I fear a global retaliation would ensue against Israel.
I hope this does not evolve into a "no-win scenario" for our brothers and sisters in Israel.
