On the 25th of January, 2003, thirty human shield volunteers and three double-decker buses left London for Iraq, picking up other volunteers throughout Europe on their way. At their peak in Iraq they numbered approximately 500.

The action’s primary goal, instigated by Ken O’Keefe, was simple; get thousands of (mostly white) Westerners to Iraq to make the bombing and invasion of Iraq politically untenable. In this goal the action obviously did not succeed, not in the least because of time constraints.
