The truth is that the president despises Israel and always has. He has spent his entire adult life surrounded by Israel-haters, from Professor Derrick Bell to Reverend Jeremiah Wright, from former Palestine Liberation Organization spokesman Rashid Khalidi to Jimmy Carter's former National Security Advisor Zbigniew Brzezinski. His current ambassador to the United Nations, Samantha Power, has suggested that the United States ought to place troops on Israeli ground to protect Palestinians from those brutal Jews.
Obama's administration has repeatedly leaked Israeli national security information in order to stop Israel from striking Iran, and Obama himself forced Netanyahu to apologize to the government of Turkey for stopping its flotilla, directed toward helping the terrorist group Hamas, in the Gaza Strip. The Obama administration sees Israel building homes in its capital city of Jerusalem as more of a threat to peace than Iran building nukes.
Obama's political philosophy dictates that Israel is a colonialist outpost offending the locals -- an unfortunate hangover from the Holocaust instead of a historic Jewish dream and possession. Obama's belief system suggests that Middle Eastern conflict springs not from religious and cultural differences but from Jewish intransigence. So Israel must be stopped. And if that means arming Iran, Obama is happy to do it. If he can while simultaneously winning himself a second Nobel Peace Prize and distracting people from his failed domestic tenure, so much the better.
