Instead, Netanyahu offered a partial and time-limited freeze and appeared to force the President of the United States to back down. For Abbas, the handshake with Netanyahu orchestrated by Obama was viewed as a humiliating climb down from his refusal to talk to the Israelis until th

years. 72. Common to every bubble is the deeply-rooted belief that this time

sound common sense rather
