Gingrich says Israel can't let Iran go nuclear Mar 4 09:15 AM US/Eastern WASHINGTON (AP) - GOP presidential hopeful Newt Gingrich says he sees no evidence that the Obama administration is taking steps to prevent Iran from building a nuclear weapon. Gingrich tells CNN's "State of the Union" that Iran is playing the U.S. leadership for fools. He says the White House is "trying desperately" to persuade the Israelis not to launch a pre-emptive strike against Iran's nuclear facilities. But Gingrich says no leader of Israel could responsibly allow Tehran to have nuclear capability. President Barack Obama is set to meet with Israeli Prime Minister Benjamin Netanyahu at the White House on Monday.
