The map above shows rings representing the distances and geography relevant to any analysis of the ability of Israel to strike Iranian nuclear reactors and enrichment facilities.  The combat radius of Israeli F-16I Sufa fighters is 2100 Km.  The combat radius of Israeli F-15I Ra'am fighters is 2225 Km.  Israeli aircraft would have to fly over Iraqi territory in order to strike Iran, as is shown by the map. 

These facts need to be analyzed in light of recent poll data in Iraq indicating that 65% of Iraqis now oppose the U.S. occupation of Iraq. (.pdf)  If we allow Israel to strike Iran via Iraq, we can expect hell on the ground in Iraq.
