The year-in-reviews have begun. Last night, 20/20 aired "the most talked about and most viewed videos of 2007." Tonight, CNN's This Week at War becomes This Year at War. CNN's "team of correspondents from critical locations around the globe will discuss topics ranging from the war in Iraq, the threat of a nuclear Iran, U.S. politics, the ongoing war on terrorism, the Middle East peace process and the impact of former Prime Minister Benazir Bhutto's assassination."

See it tonight at 7pmET on CNN or again tomorrow at 1pmET.
