SPECIAL CORRESPONDENT WASHINGTON Ex-US Defence Secretary Robert Gates blasted PM Benjamin Netanyahu, saying that his policies were ungrateful towards the US and were isolating Israel on a global level. In a meeting of the NSC Principals Committee held not long before Gates retirement, Gates argued that America had taken many steps to guarantee Israels security, but had received nothing in return, Politico reported, quoting Bloombergs Jeffrey Goldberg. Under the Obama administration, the United States has assisted Israel with intelligence, missile-defence technology and weapons.
