So who is to blame? Israeli leaders should look in the mirror. Every nation puts its own perceived self interests first. Only Israel seems to go out of its way to undermine its own interest to placate the US because of an erroneous belief that the US reciprocates. The US and Israel are allies but allies do not have identical interests. The decision of when to cooperate and share information must be made in that context.
The State Department has been anti-Jewish and then anti-Israel since before the Holocaust. The difference is that now we have anti-Semitic president. Obama supports radical Islam's obsession with the annihilation of Israel and the extermination of the Jewish people. We are living in very dangerous times.
