The TLDR of the video is that the Russian invasion of Ukraine was bad, and that Western and Ukrainian aggression didn't poke the tiger. He doesn't mention that the West could end the war tomorrow.
To be fair, I'm not pro Putin. I know Russians in Russia who are risking their safety to be peace activists, which is the correct and noble position to have in Russia. An Australian guy taking the position that Putin bad just seems easy and is doing the work of the State department.
The sheltering Nazis for decades while crushing native populations might be good reasons to hate Argentina. For more contemporary reasons, its regression towards aiding the US and other capitalist powers is pretty good. It's the least good south American country.
But OTHER than that
They also tried really hard to eliminate their black population, to the point you don't even hear anything about them.
There's also the fact that Argentina is extremely racist and have a pretty clear case of thinking they are European complex.
