Hmmm The last time I looked the President of the United States was free to negotiate with any nation without Israel's input or approval. Even the suggestion that America somehow or another is obligated to conduct its foreign affairs via Tel Aviv is nonsense. But then again the entire relationship between the US and Israel has been a one way street in favor of Israel for decades. The American people will no longer accept such one sided relationships with out countries.
