Iraq's fragmented leadership is struggling to meet the major benchmarks that it has pledged to the United States to achieve soon, with political wrangling and a chaotic legislature standing in the way.
The issue took on new urgency last week when House Democrats drafted legislation that would require President Bush to certify by July 1 and again by Oct. 1 whether the Iraqi government is making progress on security, an oil plan and constitutional amendments.
Even if the Democratic proposals never make it through Congress, pressure is mounting for the Iraqis to meet a timetable or risk losing U.S. troops and support.
But the Iraqis face a host of stumbling blocks that go to the heart of the crisis.
And recent talk of changes in Prime Minister Nouri al-Maliki's government may just increase the paralysis as groups maneuver for power.
Making al-Maliki's political responsibilities all the more difficult is the constant violence plaguing Iraq, which left hundreds of Shiites in mourning Monday at funeral processions a day after a suicide car bomber rammed a flatbed truck packed with pilgrims.
The attack on Shiites returning from weekend rites in Karbala killed 32 people.
Attacks have killed hundreds of Shiite pilgrims in the past week as they traveled to and from Karbala, where they commemorated the 7th century death of the Prophet Muhammad's grandson.
As the Iraqi government struggles to meet U.S. deadlines, the top American commander in the country, Gen. David Petraeus, told CBS News correspondent Allen Pizzey that he is also well aware of pressure in Washington to get the job done.
"We do know that there's a Washington clock, a London clock, if you will, all of these different clocks out there, and there's a Baghdad clock. They're not all moving at exactly the same rate of speed," Petraeus said.
The "Washington clock" Petraeus referred to will likely only speed up with casualty reports from Iraq continuing; a U.S. Marine was killed in combat operations in western Iraq and an Army soldier died in the Baghdad area, the military said Monday.
The Marine, assigned to Multi National Force-West, was killed Sunday in the Anbar Province, the scene of ongoing fighting between U.S.-led forces and Sunni insurgents.
The Army soldier, assigned to the Multi-National Division-Baghdad, died Sunday "due to a non-battle related cause," the statement said without providing additional details.
The clock ticking in Gen. Petraeus' ear is hardwired to Iraq's seemingly-unstoppable sectarian violence. As the bomb tore through the truck carrying the Shiite pilgrims over the weekend, a group of representatives from Iraq's neighbor countries, the U.S. and other interested partiesto discuss a remedy for the bloodshed.
Pizzey reports most of the interest at the meeting was on U.S. delegates sitting down with counterparts from Iran and Syria, but two mortars strikes close by may have helped the delegates focus on the immediacy of their challenge.
At the first meeting of the "neighbors conference" the atmosphere was good, and various committees were formed to deal with the issues going forward. But, Pizzey says, none of the delegates, and least of all the military, is under the illusion that the insurgents are clocking out and going home.
The U.S. is also pushing for constitutional amendments to remove articles which the Sunnis believe discriminate in favor of the Shiites and Kurds.
U.S officials also want Iraqis to pass a bill to set new elections for provincial governments to encourage greater public participation at the grass roots level.
So far, the only success has been a new oil law, which al-Maliki's Cabinet endorsed on Feb. 26 and sent to parliament for approval. Leaders of all main political blocs have pledged to support the bill, which lays down rules for negotiating contracts and distributing the revenues among Shiites, Sunnis and Kurds.
But parliament has not taken up the measure yet, and the deputy speaker told The Associated Press that the draft may have to be sent back to the Cabinet because al-Maliki's staff skipped some legal steps in endorsing it the first time.
Likewise, the bill on provincial elections is bogged down in procedural matters. The measure is designed to redress problems caused when the Sunnis boycotted the January 2005 election, which provincial councils were chosen.
That resulted in Shiites winning power in some areas with Sunni majorities. Shiite lawmakers are not anxious to give up those gains.
Legislation to relax the ban on former Baath party members holding government jobs or elective office faces an even tougher road.
Shiites and Kurds, who suffered the most under Saddam's Sunni-dominated regime, are reluctant to reinstate thousands of members of the party responsible.
The government provides most jobs here, and the ban effectively deprives thousands of former Baath members of a livelihood. Many are Sunnis, and the U.S. believes the current rules are driving Sunnis into the insurgency.
The main Sunni bloc in parliament wants the rules loosened so that thousands of lower-ranking party members can get their jobs back.
Ali al-Lami, executive-secretary of the government committee that screens former party members, told the AP that the factions reached a broad compromise during a meeting Feb. 28, whereby the number of Baath members under the ban would be cut by more than half.
Other former party members would be offered reinstatement or retirement with pensions, he said. Al-Lami said al-Maliki had endorsed the compromise.
But that's no guarantee of swift passage. Many Shiite and Kurdish lawmakers hold strong personal views on the issue, and most of the 275 parliament members have not seen details of the compromise since the legislature adjourned for a month in early February.
It was to have reconvened last Tuesday, but only a handful of members showed up and the session was rescheduled until Monday — when only about 50 appeared. The assembly needs half the members plus one for a quorum.
Kurdish legislator Mahmoud Othman said opinion among rank-and-file lawmakers was still divided.
Othman said he hoped that both the oil bill and changes in the Baath membership ban would be approved by July when parliament begins its summer recess.
"I think the issue of the constitutional review would take a longer time because all political groups and parties, not parliament only, are involved in this sticking issue that might shape and determine the future and the destiny of this country," Othman said.
The Shiites and Kurds agreed to consider amendments so that Sunni politicians would endorse a vote on the constitution, but the Sunnis are demanding are the very changes that the Shiites and Kurds have fought hard to prevent, and neither side shows much sign of backing down.
