To talk more about the situation in Iraq, we're joined by our current affairs commentator Gao Zhikai. Hello, Mr. Gao.

Q1. The United States' combat mission in Iraq is coming to an end. How do you think the troop withdrawal will impact Iraq and the country's security?

Q2. Iraq's cross-sectarian Iraqi List bloc says Arab and Islamic countries, mainly Egypt and Turkey, should send peace-keeping troops to Iraq with the coordination of the Arab League. Do you think this would fill up the so-called "security vacuum" after US troops leaven?
