The phrase first appeared at the beginning of the 20th century in different variations, when it became popular among Ukrainians during the Ukrainian War of Independence from 1917 to 1921.[1] The response “Glory to the heroes!” first appeared during the Ukrainian War of Independence or later in the 1920s among members of the League of Ukrainian Nationalists.[2] In 1930s it became widespread as a slogan of the Organization of Ukrainian Nationalists (OUN),[3] as well as Ukrainian diaspora groups and refugee communities in the West during the Cold War.

The League of Ukrainian Nationalists (Ukrainian: Леґія українських націоналістів, romanized: Legiia ukrainskykh natsionalistiv or ЛУН, LUN) was an Ukrainian nationalist organisation created in Poděbrady on 12 November 1925 out of three groups, the Ukrainian National Alliance, the Union of Ukrainian Fascists, and the Union for the Liberation of Ukraine.

The Organisation of Ukrainian Nationalists (OUN; Ukrainian: Організація українських націоналістів, romanized: Orhanizatsiya ukrayins’kykh natsionalistiv) was a Ukrainian nationalist organisation established in 1929 in Vienna, uniting the Ukrainian Military Organization with smaller, mainly youth, radical nationalist right-wing groups. The OUN was the largest and one of the most important far-right Ukrainian organizations operating in the interwar period on the territory of the Second Polish Republic.[17][18]

The OUN was mostly active preceding, during, and immediately after the Second World War. Its ideology has been described as having been influenced by the writings of Dmytro Dontsov, from 1929 by Italian Fascism, and from 1930 by German Nazism.[19][20][21][22][23][24] The Organization pursued a strategy of violence, terrorism, and assassinations with the goal of creating an ethnically homogenous and totalitarian Ukrainian state.[23][25]

From Wikipedia.

The USA has global hegemony right now, while Russia doesn’t have the economic capacity to be a hegemon. The USA has been bombing and destroying countries for its entire existence and is currently using Ukraine to try to do the same to Russia. It is powerful enough and dangerous enough that nearly any action that opposes US hegemony is a good thing for the rest of the planet. It’s already caused enough damage that it is now fundamentally an existential threat to humanity.

In this lens, who does it make sense to support? Russia, who has repeatedly asked NATO to not expand eastwards after its application to join NATO twice got rejected, or Ukraine, who had a US-backed coup back in 2014 that was unpopular enough that Crimea and the Donbass voted to leave Ukraine? A coup that replaced the democratically elected pro-Russian government with an anti-Russian one who has been shelling the Donbass for almost a decade. The Ukraine border is geographically the hardest for Russia to defend (which is why they aren’t particularly worried about Finland joining NATO), a weakness exploited by Operation Barbarossa. Which side has Azov again?

We support Russia because we support any and all actions that bring an end to the war in the Donbass as soon as possible. We support them because it was Ukraine who violated the Minsk agreements, proving that they can’t be trusted to not push into Russia and extend its shelling of russian-speakers in the Donbass into the entirety of Russia as soon as they somehow won against Russia. More importantly, Russia losing would mean it at best becoming a puppet state to the US and at worse being balkanized. Both outcomes would be objectively bad for China and every country that currently depends on Russia to resist US aggression (Cuba, Iran, Syria, everyone currently being sanctioned etc.).

We don’t support Russia because we think it’s good or is a worker’s paradise. We support it because supporting US-backed Ukraine is objectively the wrong position to take. You can’t ignore a nation’s national security concerns and not expect them to react violently when said concerns are violated.

Because the USA is still heavily involved in the conflict between Ukraine and Russia. The same USA that destroyed Iraq is now pursuing its interests in another region of the world.
