Car bombs in Baghdad killed dozens of people on Sunday of last week.
This is part of an upsurge in violence this year—UN figures put the number of civilians killed in attacks in Iraq from January and September at almost 5,000.
More than 3,000 were killed during 2012.
The media usually explain the attacks as simply the result of rising sectarianism. But this is not enough to explain the rise in violence because many Iraqi cities remain mixed with Sunni and Shia Muslims living together.
Any explanation has to take account of almost a decade of Western imperialist occupation.
The US built up and even established different political military groups in the country to help impose their occupation.
They fuelled instability and fragmentation which still affects Iraqi society today as different groups compete, sometimes with violence, for political control.
The US still pursues its own interests in the country it has destroyed. Baghdad has the US’s largest embassy with 3,000 staff.
Causalities of the West’s invasion and nine-year occupation are estimated by a new academic study at around 500,000 deaths from “war related causes”.
