Despite the fact that some of the terror attacks in Iraq are horrendous, the trend of those attacks is down. According to the Department of Defense:
The number of terrorist incidents in Iraq have dropped to the lowest level since March 2004....There are between 40 and 60 incidents each day in the country, sharply down from the terrorist effort in the week of the Iraqi elections in January. Even this doesn't tell the whole story. Of those incidents, roughly half have no effect. This means terrorists launch an attack, but no lives are lost, nor is any property damaged.
This could change overnight, of course, but it is good news nonetheless.
