BEIRUT (Reuters) - Leading Lebanese politician Walid Jumblatt said on Friday his country did not deserve to be accused of declaring war against Saudi Arabia, saying it was  really sad  that Riyadh had made such a statement after decades of friendship.  We do not deserve, as Lebanese, such accusations,  Jumblatt told Reuters by telephone.  For decades, we ve been friends.  Saudi Gulf affairs minister Thamer al-Sabhan earlier this week accused the Lebanese government of declaring war on Saudi Arabia, lumping Lebanon together with the Iran-backed Lebanese Shi ite group Hezbollah as a hostile party.
