Iranian parliament speaker Mohammad Bagher Ghalibaf said the Strait of Hormuz is a pillar of Iran’s national security and Tehran must preserve Iran’s existing arrangements in the vital shipping route. In an address to the nation he said Iran is engaged in a complex struggle with the United States and must remain prepared to fight; he added US strategy toward Iran has not changed and aims not only to weaken Iran but to sow domestic divisions. Ghalibaf said Iran’s policy in both conflict and negotiations should be grounded in realism, national interest and a long-term perspective.(金十数据)
