Yesh Atid leader MK Yair Lapid addressed The Jerusalem Post Diplomatic Conference in the capital on Wednesday, calling on the Palestinians to 'Grow up already,' employing a quote from Alan Dershowitz. 'You want freedom? Free yourselves from the past and build yourself a future,' Lapid said. 'Self pity is not a very efficient policy,' he added. Lapid said that the Palestinians should take a page from the Jews after the Holocaust. 'We didn't look for someone to blame after the Holocaust, we searched for a way to change it.'
