Iraqi troops take over Green Zone security

The video discusses the symbolic replacement of the US flag with the Iraqi flag over the Republican Palace in Baghdad's Green Zone, marking a significant step towards Iraqi sovereignty. The transfer of power ceremony, devoid of American officials, is highlighted as a memorable event by Prime Minister Nouri al Maliki. This day is now a national holiday, symbolizing the beginning of Iraq's self-determination. The transfer coincides with the expiration of the UN mandate for foreign troops, although a significant number of US military personnel remain under a cooperative framework with Baghdad. Full sovereignty is expected by the end of 2011, when the last coalition troops are scheduled to leave.
