Teribus, Israel has been implicitly threatening the entire Muslim world in the Middle Eastern area with extermination, by means of at least 100 nuclear weapons, for some considerable time now. Of course they don't say so openly in public international dialogue, they don't even admit they have the nukes, but they have made it quite clear to the Muslims through quiet diplomatic channels that that is what will happen if, for example, they should lose a conventional war and find Arab armies crossing their borders into Israel. And everyone knows it.

Their message: "We will annihilate you. Depend upon it. Mecca, Medina, Cairo, Ryadh, Tehran, Damascus, all your cities...all will go POOF! And you will all die."

And the Muslims know it well. You are mistaken that the Israelis have not threatened to wipe out other countries. They have. They just threaten quietly...like when the Mafia sends a cold-eyed guy in a suit to let you know exactly what will happen if you cross the line.
