Ted Cruz on Monday mocked Donald Trump's grasp of history and promised not to be neutral in a negotiation between Israel and Palestinians, something Trump has said he would do if elected president. At his speech before the American Israel Public Affairs Committee, Cruz started by highlighting a mistake Trump made during his own speech just minutes earlier. "Perhaps to the surprise of the previous speaker, Palestine has not existed since 1948," Cruz said, drawing mixed laughter and applause from the crowd.
