The Americans do memorials better than most, probably because as the world's policemen they have more to remember.
The expansive Arlington Cemetery, just across the Potomac River from Washington DC, is the most hallowed ground in the United States where the war dead going back to the Civil War are buried. It stands as a stark reminder of the futility of war, fought by young men and women following the stroke of a pen in the Oval Office.
And in New York in downtown Manhattan stands the impressive Memorial Plaza commemorating 9/11, dotted with almost 400 white oak trees where the daily crowds of mourners and tourists are drowned out by the crashing waterfalls, the largest man made falls in the United States.
The names of each of the almost 3000 people who perished in the Word Trade Centres in 2001 are honoured in bronze around the twin memorial pools. The birthday of everyone of them is remembered daily with a white rose placed on their name.
It's certainly a place where you reflect on the wasted lives and most of us remember exactly what we were doing when the terrorist hijacked jetliners struck.
