What If the Mullahs Mean What They Say?

Then a nuclear Iran means the end of Israel:

Iran's nuclear program seeks first-strike capability against Israel, a leading strategist said.

The Israeli strategist and former intelligence officer said Iran believes it could destroy the Jewish state with one nuclear weapon.

"Iranians believe that it holds, may hold, a first strike capability against Israel once it has a nuclear capability," said Shmuel Bar, director of studies at the Institute of Police and Strategy.

Iran believes "that Israel is a one-bomb country, one bomb from the point-of-view of the receiving side; that the U.S. would not intervene against Iran under such conditions; and all of that with apocalyptic zeal may result in actual use of nuclear weapons," he said.

As I've noted previously, we have given Iran no reason whatsoever to believe we will retaliate for their destroying Israel. After all, we have ignored their killing our own citizens and attacking our sovereign soil. If we are unwilling to defend ourselves, why would we defend Israelis?
