Khamenei adviser: If Assad falls, Iran is next in line

"If [Syrian President Bashar] Assad falls, Iran and Iraq are next in line," said an adviser to Iran's Ayatollah Ali Khamenei on Saturday to Iranian news agency Mehr.
The adviser, Ali Akbar Velayati, said Iran has been supporting the Palestinians, Hezbollah and the Assad regime in Syria in order to support "the chain of resistance."
“The Zionist regime was defeated against not so advanced Fajr 5 missiles. Islamic Jihad pinned down 3 million people in Tel Aviv to bunkers" with missiles provided by Iran, he said.
