This is not good news. The New York Times' Eric Schmitt has the story:

Iraqi insurgents are using roadside bombs with increasing effectiveness to disrupt American military operations in Iraq, the deputy commander of American forces in the Middle East said Wednesday.

The officer, Lt. Gen. Lance Smith of the Air Force, also said that one of the most important militant leaders driven out of Falluja was now probably operating in Baghdad. Speaking to reporters at the Pentagon, General Smith said the Jordanian insurgent leader Abu Musab al-Zarqawi was still orchestrating attacks against American and Iraqi forces and communicating with confederates, despite having lost many of his top lieutenants and his base of operations during the offensive in Falluja last month.

There's not much to say about this aside from the fact that it is really disheartening news. If the nation had gone to war with the needed troops, perhaps we would not be facing the endless violence that currently afflicts us. Regardless, something needs to change in Iraq, and I don't know if that's a massive increase in troops--whether American or from another country--a change in the civilian leadership, or something else, but something must be done to ensure the safety of the men and women on the ground.
