Prague Declaration). It is a strong document.

People navel gazing won't help. I wrote back then that it "never ceases to amaze me how Nazism, Hitler, Nazi Germany etc are rightfully vilified yet the Soviet Communist regime is barely mentioned, a willful forgetfulness; they even call it Stalinism presumably to not taint 'Communism': I guess with so many left wing MPs and MEPs with their past in the Communist parties they feel another name is needed."
The Prague Declaration has not been without it's critics but "Those who neglect their past have no future".
