The Israeli and American air forces initiated a joint exercise, Juniper Oak, which appears to prepare Israeli Defense Forces for a potential strike in Iran. The exercise involves simulated airstrikes on deep strategic targets, achieving aerial superiority and cyber defense against various threats.
  

Key Points: 

1. The Juniper Oak exercise simulates airstrikes against “strategic targets in depth,” suggesting it is a rehearsal for potential attacks on Iran’s nuclear facilities.
2. The drill also focuses on “achieving aerial superiority in the region” and preparing for cyber defense against various threats.
3. During the exercise, Israeli Air Force (IAF) fighter jets are refueling from an American Boeing KC-46, a plane critical for Israel to conduct potential major strikes against targets in Iran, which is significantly outside the normal flight range of Israeli jets.
4. This exercise is part of a series with the US Central Command, which continues and strengthens the operational cooperation between the militaries.
5. Israel and the US regularly conduct various training drills together, including air force exercises and missile defense drills.
