Of course it was positive to have the German wreath laid at the cenotaph.
My father was in the Med Fleet in WW2, luckily he was too young to be involved in the Battle of Crete in 1941 where so many allied sailors, soldiers and Greeks were killed. The Battle is commemorated at many events on Crete around 21 May each year. There are commemorations is many small villages, which have a sign giving the name of the Martyred Village. The memorials in those villages list all the local men and boys aged 14 - 80 who were killed by the Nazi's in retaliation for resistance.
At the 70th anniversary of the Battle of Crete, as well as the wreaths laid by members of the allied services and Greek resistance fighters, young German paratroopers laid a wreath. There was a silence as they marched forward, then spontaneous applause in a spirit of reconciliation.
MaudLillian, I don't believe that WW2 can be put into the category of a 'stupid conflict'. I don't know how else Hitler and his murderous regime could have been stopped.
