There's that emotional thinking again. _We_ started that war when we funded a coup there in 2013 and hand-picked[1] their rabidly anti-Russian government. We also funded and condoned their neo-Nazis, without whom none of this would work [2]. Mostly Russian-speaking Eastern Ukraine disagreed with that kind of thing. After all, it was mostly them who elected the president that we overthrew. West Ukraine started shelling east trying to subdue them, calling it an "anti-terror operation". Russia provided "lethal aid". Things escalated. The conflict did not start in 2022. Suggesting that we can just go ahead and build tactical nuke bases right next to where ~70% of Russia's population lives, and Russia should just roll over and let it happen, is idiotic and reckless.
As if Trump and Vance's demand that Zelensky abase himself in front of them isn't "emotional thinking"; as if cutting off military aid because Zelensky didn't bow and scrape isn't "emotional thinking".
As if taking the hundreds of nuclear red lines Putin has laid down and allowed to be crossed without a nuclear response, isn't "emotional thinking".
