The target would be the NATO missile defense shield located in Turkey, but such an attack would still be a strike on the territory of an un-involved third country. That could carry unintended consequences for Iran, which is not taking into account in this round of saber-rattling that Turkey just might also take umbrage at that sort of thing.
"Iran threatens to hit Turkey if US, Israel attack," from the Associated Press, November 26:
TEHRAN, Iran -- A senior commander of Iran's powerful Revolutionary Guard says the country will target NATO's missile defense shield in Turkey if the U.S. or Israel attacks the Islamic Republic.
Gen. Amir Ali Hajizadeh, the head of the Guards' aerospace division, is quoted by the semiofficial Mehr news agency as saying the warning is part of a new defense strategy to counter what it sees as an increase in threats from the U.S. and Israel.
He says Iran will now respond to threats with threats rather than a defensive position.
Tehran says NATO's early warning radar station in Turkey is meant to protect Israel against Iranian missile attacks if a war breaks out with Israel.
Turkey agreed to host the radar in September as part of NATO's missile defense system.
