It’s never one thing but more like a pie chart. If we looked at the biggest chunks on the pie chart, they would be the things I outlined and take up the majority of the chart. Hurting Russia is nice, you’re right, but Russia is not a real threat. Other countries don’t need to join NATO. Russia does not have the capacity to properly invade Ukraine, the poorest country in Europe right next to their border. The only real threat Russia has is nuclear weapons, and should Russia start nuking non-NATO countries I don’t think Article 5 is going to matter - the US is going to respond.
I view Ukraine war a lot like the Spanish Civil war in 1936. Nice playground to test out new military tech. Nevermind the hundreds of thousands of young men who are going to die or be permanently maimed, Ukraine having their demographics crippled for the next century, and the hundreds of millions of poor across the world who are suffering under rising inflation due to things such as food supply
I agree war in Europe is very “symbolic” but that doesn’t matter in a geopolitical sense. It’s only useful as a propaganda tool in order to justify the eternal prolongation of the above mentioned destruction
