We owe Israel, the world's most belligerent, lawless, and intransigent nation, absolutely nothing! And although there is rampant treason in my country (yes, I'm at you, AIPAC and Congress,) Obama answers only to the people of the United States of America! He does not answer to Israel, nor should he. And considering the fact that Israel has not only flagrantly disobeyed understandings they made, but also international law (on a daily basis, for decades, no less,) neither Israel nor its apologists have any room whatsoever to speak about going back on one's word!
