The white-blue-white flag is a symbol of opposition to the 2022 Russian invasion of Ukraine that has been widely used by Russian anti-war protesters. By extension, it has also been used as a symbol of opposition to the Putin regime in Russia
Several people created the idea of the white-blue-white flag independently, almost simultaneously shortly after the 2022 Russian invasion of Ukraine started on 24 February 2022.
Like the title says, I'm proposing the white-blue-white flag of the Russian opposition be added to the list of national flags. Do it to show solidarity with Russian NS users who oppose Vladimir Putin.
