The evidence is very clear that the US and its allies support withdrawl from Iraq. After more than a decade of American and coalition forces keeping a heavy presence in the country, I'm sure they are just as happy to see us go as we are. The forces have done a lot for the Iraqi people, now it's time for the Iraqi people to take charge and for the Western world to bow out.
US troops have officially withdrawn from Iraq (mostly), and doing was certainly unpopular in the country. The Iraqi government was largely set up and supported by the US, and as such derived a huge amount of material and political support from it. The Iraqis are far from being able to secure their own country.
