I posted this on the day of the invasion and I think it aged pretty well.
Russia is not attacking Ukraine in response to actions of the USA since then, that’s an Americocentric delusion. This is not happening because Ukraine wanted to join NATO, it’s happening because they are outside NATO, which is not the same thing at all. Russia is not driven by fear of NATO strength, it is driven by perceptions of western weakness. Russia believes the cultural, military and geopolitical balance has tipped in their favour, expecting the west will respond to their invasion of Ukraine today with nothing more than official grimaces. I hope they are not correct about that but we will soon see.
Putin is motivated by oft stated imperial ambitions to Make Russia Great Again, to ‘restore’ Russia to its imperial boundaries with Moscow as the New Rome (yes, they really say that); Ukrainian rejection of that notion and assertion of their own identity is therefore intolerable. But reject ‘the Russian world’ they did, because Ukrainians do not wish to be ruled from the Kremlin even indirectly. That is why they overthrew Russia’s favoured oligarch and sought to chart their own course in the world.
That is what this war is about.
I still see things much the same and am delighted my fears about a lack of meaningful support for Ukraine were misplaced.
