The right wing Jewish groups in the United States will have a hissy fit and that will be the end of that. It's the oddest thing that there is a group in the USA that purports to support Israel and then denies the opportunity for any real positive change for Israel. This lobby group has a lot of power of influence through a lot of propaganda, threats and intimidation.There are a lot of big Jewish campaign donors too. Our government (the US) is controlled for the most part by various lobbies, Wall Street, insurance companies, defense contractors, drug companies, agribusiness etc. That's just the reality of the situation. It ain't the democracy you read about in the text books. So, watch what happens when President Obama and Secretary of State Clinton try to move the process along. Just read the NY Times about what the Israel lobby groups do. No real pressure can ever be put on Israel because of the Jewish lobby in the USA.
