IRAQ-KUWAIT BORDER, Kuwait - The last US forces left Iraq and entered Kuwait Sunday, nearly nine years after launching a divisive war to oust Saddam Hussein, and just as the oil-rich country grapples with renewed political deadlock.
The last of roughly 110 vehicles carrying 500-odd troops mostly belonging to the 3rd Brigade, 1st Cavalry Division, traversed the border at 7:38 am (0438 GMT), leaving just a couple hundred soldiers at the US embassy, in a country where there were once nearly 170,000 troops on 505 bases.
It ends a war that left tens of thousands of Iraqis and nearly 4,500 American soldiers dead, many more wounded, and 1.75 million Iraqis displaced, after the US-led invasion unleashed brutal sectarian killing.
The last group of vehicles transporting US troops out of Iraq left the recently-handed over Imam Ali Base in Nasiriyah, southern Iraq, at 2:30 am to make the 350-kilometre (220-mile) journey south to the Kuwaiti border.
They travelled across a mostly-deserted route, which US forces paid Shiite tribal sheikhs to regularly inspect to ensure no attacks could take place.
Five hours later, they crossed a berm at the Kuwaiti border lit with floodlights and ringed with barbed wire, whooping and high-fiving in joy having left Iraq.
"(It's) a good feeling ... knowing this is gonna be the last mission out of here," said Private First Class Martin Lamb, part of the final "tactical road march" out of Iraq.
"(It's) part of history, you know - we're the last ones out."
The withdrawal comes as the country struggles with renewed political deadlock as the Iraqiya bloc, which won March 2010 elections and drew most of its support from minority Sunnis, said it was boycotting parliament to protest Prime Minister Nuri al-Maliki's centralisation of decision-making.
The bloc, which controls nine ministerial posts, has not, however, pulled out of Iraq's national unity government led by Maliki, a Shiite.
"We can no longer remain silent about the way the state is being administered, as it is plunging the country into the unknown," the bloc, which holds 82 seats in the 325-member legislature, said in a statement on Saturday.
Iraqiya said the government's actions, which it claimed included stationing tanks and armoured vehicles outside the houses of the bloc's leadership in the heavily-fortified Green Zone, "drives people to want to rid themselves of the strong arm of central power as far as the constitution allows them to."
Provincial authorities in three Sunni-majority provinces in north and west Iraq have all moved take up the option of similar autonomy to that enjoyed by Kurds in north Iraq, drawing an angry response from Maliki.
