FRANCE24: Call it rebuttal time. After Donald Trump and Benjamin Netanyahu, the turn of Iranian president Hassan Rouhani to address the UN General Assembly. He needled Trump, picking up on his "rogue state" rhetoric while defending the nuclear agreement. Since Rouhani''s last UN speech he''s been re-elected, but how much of a mandate does he have in a nation where final say goes to clerics and to their ageing leader, Ayatollah Khameinei? It''s clear Rouhani doesn''t call the shots on the battlefield.
