"Hopes were dashed...?"
Yes, it was inciteful to the Arabs. With the Congressional admiration and standing ovations publicized all over the world, sent a message to the Arabs and Europeans. Netanyahu must hold very very tight to his words and NOT loose grip on our Land.
"One of the widely articulated goals of his trip, where he met with President Obama and addressed Congress, was to find a way to lure the Palestinians back to direct negotiations, thereby preempting their plan to approach the United Nations in September for recognition of statehood within the pre-1967 lines."
"a way to lure Palestinians back..." the goal changed because of Obama's Thursday speech. How many times can one discuss and rehash Arab demands intending to weaken Netanyahu (any of Israel's Prime Ministers) and squeeze the Israelis further into an untenable and dangerous situation. Their announced goal and what is written in their charter (never to be altered) is the destruction of the Jewish Homeland.
Why do we have to 'lure' the Arabs onto our Land and make them into a state inside our legal borders? Listen to what they say to their people. Realize how they teach their children to hate the Jews. Watch what they do. They have brought violence, hatred, and slaughtering to a universal norm. So what if they lived here once. So did the Canaanites, and they were banished by G-d from the Land with the Land given to the Jews. We are the sole inheritors caretakers for this Land. The Christians did not supersede us and the Mohammedans did not supersede us, no nation superseded the Jewish Nation on Earth!
The Temple Mount, Har HaBayit, and Yerushalayim has belonged to the Jews since the time of Abraham Avinu. No matter who tries to destroy and malign our history it does not change the universal truths.
"Instead, the Palestinians now say, Mr. Netanyahu’s speeches persuaded them that they had no negotiating partner. They plan to intensify their United Nations efforts, leaving Israelis worried about increasing international isolation and pressure."
Palestinians: Negotiating means not compromising, not giving in on one inch, and pushing for more and more. This is NOT negotiating.
