...I don't think multiple bombing attacks that have resulted in nearly forty dead should be something taken lightly:

Nearly 40 killed in Baghdad blasts

BAGHDAD, Oct. 27 — Car bombers struck the international Red Cross headquarters and four police stations across Baghdad on Monday, killing about 40 people in a spree of destruction that terrorized the Iraqi capital on the first day of the Muslim holy month of Ramadan, according to police and Red Cross reports.

THE RED CROSS said 12 were killed there, and police said 27 were killed in the police station bombings, most of them Iraqis. The U.S. military confirmed that among the dead was one American soldier killed at a Baghdad police station.

The bombings came hours after clashes in the Baghdad area killed three U.S. soldiers overnight, and a day after insurgents devastated a hotel full of U.S. occupation officials with a rocket barrage, killing a U.S. colonel and wounding 18 other people. U.S. Deputy Defense Secretary Paul Wolfowitz was in the hotel, but was unhurt.

It was two days of violence unprecedented in this city of 5 million people since the end of the U.S.-Iraq war last April, attacks aimed at the American-led occupation and those perceived as working with it.

I don't regard a coordinated terrorist attack that results in nearly forty dead to be something of "limited effect." Makes me wonder how many need to die for you before consider that it had an "effect."
