Israel seeks "air corridor" over sovereign Iraq

According to Ha'aretz, Israel wants the way clear for an attack on Iran but who is Israel negotiating with for this corridor?

Israel is negotiating with the United States over permission for an "air corridor" over Iraq should an attack on that country's nuclear facilities become necessary, the British newspaper The Daily Telegraph reported Saturday.

Military authorities would need permission from the U.S. Department of Defense for any such operation

But not from sovereign Iraq.
