A half year after the U.S. military left Iraq, dire predictions seem to be coming true: The country is mired in violence and the government is on the verge of collapsing. With no relief in sight, there's growing talk of Iraq as a failed state as al-Qaida's local wing staged near daily attacks that killed at least 234 people in June.

Iraq no longer suffers widespread retaliatory killings between Sunni and Shiite extremists that brought the country to the brink of civil war. But the spike in violence heightens fears that Iraq could limp along for years as an unstable and dangerous country.

June was the second-deadliest month since U.S. troops withdrew from Iraq in mid-December as insurgents exploited the political struggles between the country's ethnic and sectarian factions. More significant than the numbers was the fact that insurgents appeared able to sustain the level of violence over a longer period than usual. There was a major deadly bombing or shooting rampage almost every three days, many targeting Shiite pilgrims.
