Pat Lang explores some of the ramifications of Bush’s last –it might seem his only– good deed:  rejection of an Israeli request for overflight permission and perhaps military assistance in bombing Iran’s nuclear reactor.  There’s been very  little about this in the mainstream press– though it’s the kind of major incident that history often  turns on.  Lang’s key point: we have a defense treaty with Iraq which allows and obligates us to defend Iraqi airspace. Would we defend it against Israeli overflights?
