Israel doesn’t need to go through Iraq. All the Israeli’s have to do is utilise Saudi airspace. The Saudis if they got in the way would only result in lots of plinked Saudi F-15s and Tornado fighters. The Israelis can take out Tabuk airfield in western Saudi and maintain a corridor for their strike force.
A huge operation, but one that would allow for their Boeing 707 tanker fleet to loiter protected by fighter aircraft. The Saudis would be hamstrung as to what to do. The only problem is that it would take a huge operation to take out all the Iranian nuclear related sites. The Bushehr reactor is due to go on line by the end of this year according to Iranian press. I don’t think that Israel has any option but to destroy Bushehr before the Russianssupply the fuel.
True, but a much longer route otherwise and fraught with complications with the Saudis, some of which you pointed out.
