What is Iran's third threat against Israel and what prompted their previous attacks?

Iran has openly threatened a third strike against Israel, with IRGC Deputy Commander Ali Fadavi announcing an attack codenamed 'Operation 2 Promise 3' that would happen 'at the right time.' This threat follows two previous significant missile attacks by Iran on Israel within the past year. In April, Iran launched over 300 missiles and drones toward Israeli military installations in retaliation for the killing of two Iranian generals. In October, Iran conducted 'Operation True Promise,' firing approximately 200 missiles in response to the assassination of key Iran-backed leaders, including former Hezbollah chief Hassan Nasrallah. This third threat comes amid rising tensions with both Israel and the US.
