For one thing, they didn't state an intention to make it happen. They said they think it should happen, and secondly, they were talking about the political entity (like the political entity of the Soviet Union), not the people or the physical land area itself. In fact, they themselves said they were using that term to mean they would like to see in Israel what happened to the Soviet Union. That did not happen with nuclear weapons. It happened politically. And that is what Iran was saying it wanted. It also did not state any intention to do anything to make that happen.
