Two Historical Breaks in Iran's Destiny: From Arab Conquest to Islamic Revolution

I'm ready to translate the Persian text to English while maintaining its exact structure and markers. However, I notice you've only provided a headline/title without the full news summary content.

The headline translates to:

**From the Arab Conquest to the Islamic Revolution; Two Historical Breaks in Iran's Destiny**

Please provide the complete Persian news summary (including the ▸ lead paragraph, • bullet lines, and. coverage-difference paragraph) so I can translate the full text while preserving its exact structure and formatting.
