Threat?

This sentence appears twice in this article: "Israel sees Iran's nuclear development as a threat, due in part to Iranian President Mahmoud Ahmadinejad's calls for Israel to be destroyed." Notice that "due in part" appears also twice. What does that mean? That if Ahmadinajad did not resort to his bellicose rhetoric, Israel would be fine with a nuclear Iran? Does that mean that witout threats, Israel would not oppose nuclear Syria or Lebanon? Is there a propaganda by a state more stupid and more deceptive than that of Israel? I even remember when Israeli propaganda was much less dumb than it is now. Don't get me wrong: I watch with relish and glee the growing signs of the demise of that usurping entity.
