I have a picture on my PC at home of an Israeli F-15I breaking-off from a USAF KC-10 refueling boom. I saw the pic on an Air Force website, and at the time thought, "Hmmm...Why would the Israeli Air Force need to have the ability to refuel mid-air? Long range mission training, perhaps?" (I suspect regular airborne patrolling may require mid-air refueling...I don't know.) At any rate, I kept the picture as a reminder and symbol of Israeli resolve to do whatever is necessary to defend Israel BEFORE an aggressor strikes.
The new F-15Is and F-16Is are equipped with special Israeli made fuel tanks so those jets are capable reaching targets as far as Afganisthan, without refuling.
Iran is within range.
