OK, I'll take that as a No.
In fact Iran has been threatening Israel with nuclear annhilation since the Ayatollah Khomeini (he should rot in hell). This has been a consistent theme of the Iranian leadership, repeated just this week at the UN. In the face of that, and evidence Iran is pursuing a bomb, it makes perfect sense for Israel to guarantee its own security.
Do you think Israel has not been consulting the US? What planet do you live on?
Do you think that Netanyahu has cleared his speeches through the U.S. State Department?
Do you think he needs to? What other leader of a country does such a thing?
