TEHRAN - Unlike the United States, Iran is prepared for a long war, Iran’s top security official said on Monday, insisting that Iran has not initiated the war as in the past 300 years.

Israel and the United States started an unprovoked and illegal war against Iran on Saturday. 

"Just as in the past 300 years, Iran has not been the initiator of war, and our brave armed forces have not conducted any attacks except for defense, we will resolutely defend ourselves and our 6,000-year-old civilization, regardless of the costs," Ali Larijani wrote on his X account. 

Larijani added, "We will make our enemies regret their miscalculations. Iran is prepared for a long-term war, unlike the United States."
