TEHRAN -- President Masoud Pezeshkian said Sunday that national unity and internal cohesion are the main source of Iran’s strength, warning that enemies would not dare strike the country if its people stand together.  Speaking at a National Children’s Week ceremony in Tehran, Pezeshkian recounted a parable about a wise man and his sticks, telling children that “if we are together, no force or enemy can bend or defeat the will of our nation.”
