I was really referring to Western Europe. Eastern Europe almost across the board recognizes the sacrifice of the Russian people to free them from Nazi Germany. Obama didn't go, Merkel didn't go, Cameron didn't go, Hollande didn't go. No instead India and China show up along with Central Asian and Eastern European leaders. Speaks a lot about who cares about the historical sacrifices made in WWII.
Czechia and Slovakia are part of west Europe. Although Merkel went in 2010, I don't see why she should - it's obviously kind of awkward (same deal with a few other countries, like Italy, which didn't go in 2010, either).
