Cardiff locals held an anti-war vigil this weekend to mark the 10th anniversary of the huge demonstration against the invasion of Iraq in 2003.
CND Cymru vice-chairman Dr John Cox said: "In the face of this overwhelming, universal cry for peace and another way of solving conflict, the US and British governments repeatedly lied and invaded Iraq.
"US and British interventions are not motivated by human rights but by economic interests, yet the attack on Iraq served to make Britain a poorer country."
Adam Johannes of Cardiff Stop the War said: "Ten years on, I look back in anger. The war happened. A million Iraqis lost their lives.
"We see racism against Muslims whipped up and a bonfire of civil liberties. However the Arab spring shows that people power can change history and I hope as governments continue to wage war on the poor at home and abroad we will once again see millions in the streets."
