The war in Iraq is in sharp focus for millions of Americans this week, and events on the ground may explain why. Wednesday was the deadliest day for U.S. troops. 31 were killed in a helicopter crash. Meantime, new video of another American hostage was released as Secretary of State designee Condoleeza Rice faced another day of tough questions about her role in the march to war. This week`s events come as Iraq prepares for democratic elections this Sunday.
