Hello,
I am most sure that 99,9% of German Wikipedians are aware what was necessary to end World War II: destroying the National Socialist German Workers' Party. With Hitler or another party member being in rule, peace was impossible. (I say this with my mother''s family having been refugees, and my father's family having suffered from the Allied bombings.) Eventually, the civil society of Germany understood how the war and all its consequences came into existence: "Because we gave in 1933 power to the wrong people." The inofficial state motto became "Never again!", and in this spirit following the horrors of the Holocaust, German Wikipedians edit Wikipedia. Never again! is now.
Kind regards, Ziko
