Last week saw the 20th anniversary of an extraordinary and unique day in world history, 15 February 2003. It was the day when tens of millions of people marched in 780 cities around the world in protest against the proposed war by Britain and America, against Iraq.

Julie and I travelled up to London in a coach from Burgess Hill. We marched in a crowd of hundreds of thousands, (it turned out to be between one and two million) united in a common feeling of opposition to war and with an expectation that such a huge expression of public opinion could not be ignored.

The millions of marchers were right. Yet on 18 March 2003 hundreds of British MPs voted for war.

The ruthless and immense bombing campaign was an outrage against humanity and a shameful blot on Britain’s reputation. Iraqi society was destroyed. With police and military removed terrible lawlessness erupted. Three million refugees fled Iraq, including Christians who had been protected under the rule of Saddam Hussein. Terrorism was provoked.
