Five months after an election Iraqis hoped would underpin governance, Al-Maliki told Reuters Iraq's security was stable and said investor confidence had not been shaken by lengthy and so far fruitless talks for a coalition government.
But he said that his opponents were attempting to weaken the premiership and said this could destabilise Iraq and bring back militants linked to Al-Qaeda as well as the militias that were involved in Iraq's sectarian slaughter in 2006-07.
A March 7 parliamentary election produced no clear winner, leaving Al-Maliki and secularist ex-Prime Minister Iyad Allawi battling to form a majority coalition as Iraq tries to ramp up production from its world-class oil reserves and rebuild an economy ravaged by war.
"They are saying there is a broad objection to Al-Maliki. But I know that there will be greater objections to (other) candidates," he told Reuters in an interview on Friday.
"Yes, I am part of the problem but I didn't create the problem," he said. "I want to solve the problem."
Al-Maliki's largely Shiite State of Law coalition won two seats fewer than Allawi's Sunni-backed, cross-sectarian Iraqiya in the vote but then merged with the third-place finisher, the Iran-friendly Iraqi National Alliance, to form a Shiite bloc.
But the Shiite allies have not been able to agree on a nominee for prime minister. INA said last week it was rejecting Al-Maliki and halting talks until his bloc offers another candidate.
Al-Maliki said he was in "serious and strong talks" with rival Allawi's Iraqiya, the Kurdish bloc and smaller parties, but was open to a reunion with INA, his traditional ally.
"We don't want to exclude them from coalition formation. They should come and take their share if we form the government," he said at the prime minister's residence.
Al-Maliki said the government impasse posed no risk to investors, citing projects to set up power generating capacity.
"We don't have any problem," he said. "Investments were not affected and will not be affected."
He rejected critics who suggest the drawn-out government formation talks - which in a few days will be longer than those after the 2005 election, when sectarian violence exploded - have opened the door to a renewed insurgency.
Iraq is plagued by bombings, assassinations and other attacks by Sunni insurgents and Shiite militias but Al-Maliki lauded the work of Iraq's nascent security forces and said the attacks had not worsened during the impasse over a government.
However, "I am convinced if there is a weak PM, someone who does not have the support of the political leadership and political blocs, the risks will be big for the unity of Iraq, for security," he said. "The militias will return, Al-Qaeda will come back, there will be conflicts."
With Washington planning to cut down to 50,000 troops by month's end from just under 65,000 now as it formally ends combat operations on Aug. 31, Al-Maliki said it was too early to talk about whether the US stay in Iraq should be extended.
That would require a change in the negotiated security pact between the two countries, which says US troops should be gone by the end of next year.
"The US cannot keep bases unless Parliament decides they will stay ... the PM cannot decide on this. He can make a proposal and Parliament will decide on this," Al-Maliki said.
"I don't want to talk about this. It's too early. We still have a year and four or five months. God willing the situation will change and the next prime minister will not have to make such a proposal."
Al-Maliki said Iraqi forces were "100 percent in charge" of the nation's security. "The security situation is stable. I don't say there are no attacks. There are. But there is no deterioration. Rather there is progress."
Al-Maliki, who rose from relative obscurity to win the premiership after long coalition talks following the 2005 election, said regional and international interference in Iraq had "complicated" government formation and "if this doesn't stop there will be no government."
"Iraq is not a small country you can force an agenda upon. Those who fear the influence of Shiites, or influence of Iran, are wrong," Al-Maliki said. "They don't know the Iraqi Shiites. These are citizens who defend their nation and fight for it."
