Today marks the 20th anniversary of the start of the Iraq war.
In the minds of many, it was a needless, unjust invasion founded on a claim - which proved to be wrong - that Saddam Hussein had weapons of mass destruction.
Many died, mostly Iraqis. The US lost an estimated 4,487 soldiers, while the UK lost 179 and other coalition forces lost 139. Figures for the number of Iraqis who died vary from between 90,000 to more than 600,000.
