Traveling 20,000km to die for a cause that is both evil and doomed, achieving nothing, doing his small part in making the world a slightly worse place. The most pointless application of personal bravery in human history. Does Australia not have any problems of her own?
A teenager from Kherson oblast whom the Ukrainian government was listing as "kidnapped and genocided by the evil ruZZian regime" was discovered to be a volunteer in the Armed Forces of Russia.
He was 15 when the war started and Kiev started claiming that he was "deported to Siberia" and whatnot. Now he is 19 and has enlisted with the Russian military. The Ukrainians found his social media and discovered that this "stolen child" was posting pro-Russian stuff and wearing Z merch all along; the "Save Ukraine" foundation even contacted him and he told them to fuck off and that he has always been a Russian patriot.
I think you can be anti-Russia and still a somewhat intelligent and morally coherent person. There are people in whose ethnic, religious or even financial interest it is to be anti-Russian and support war against Russia. They are just normal adversaries. Sometimes you gotta kill them when it comes to that but that's life. However, I don't believe that you can be sincerely pro-Ukrainian and still a good person. Actually supporting the Kiev regime and believing they're "the good guys" (sincerely, not for personal profit or purely anti-Russia reasons) means that you are morally defective and evil, or such a stupid NPC biodrone that you're basically outside of any ethical consideration.
I do somewhat envy the Iranians for their competent escalation management, but they're also lucky that there's no big country right next to them that is full of suicidal idiots willing to die for US interests in their millions, otherwise things would look differently
It's quite bizarre how many people have managed to convince themselves that the Ukrainians have equal or even superior capabilities when it comes to the air war
A full-scale US military intervention to crush drug cartels in Mexico would be the only morally defensible use of the US military in living memory, but it's also the least likely to happen.
